Effect of Systemic Lidocaine on Postoperative Early Recovery

Introduction

The mind neoplasm, as a standard neurosurgical illness, has varied medical manifestations as a result of completely different pathological sorts, areas and growth charges. When it comes to supratentorial tumor therapy, craniotomy is presently the primary selection. Extended intracranial surgical procedure, probably leading to delayed postoperative restoration, might result in ischemia and hypoxia in mind tissue, explosive improve of inflammatory elements, postoperative ache, postoperative nausea and vomiting (PONV), and many others. Anesthesia acts as a key hyperlink through the surgical procedure, together with optimizing mind metabolism and bettering mind oxygenation. With most consideration being paid to excessive charges of incapacity after mind tumor resection, equivalent to hemiplegia and aphasia, nevertheless, sufferers’ subjective emotions haven’t but been taken severely, and have even been ignored by clinicians. Among the many bulk of recovery-evaluation scales, the QoR-40 scale is exclusive for its applicability, reliability, validity, responsiveness, accuracy, acceptability, interpretability and feasibility. This questionnaire was designed to evaluate well being standing as a complete and restoration high quality from particular dimensions, and has been efficiently utilized in cranial surgical procedure sufferers.^1–4 In our research, QoR-40 scores have been set as major final result measures.

Because the mainstay of ache therapy, opioids have develop into an integral a part of surgical procedure, regardless of inevitably inflicting “nausea and vomiting”, “hyperalgesia”, “drug resistance”, “delirium”, and many others. Due to this fact, an intraoperative opioid-sparing technique mixed with the nerve block method and the adjuvant turns into a clever selection.^5–8 Sumathi et al. discovered that lidocaine might enhance the brink of airway stimulation response, thus inhibiting extreme improve in intracranial stress brought on by choking throughout extubation, which was of nice profit to sufferers with mind neoplasm.⁹ Throughout common anesthesia, systemic lidocaine (1.5 mg/kg or 1.5–2 mg/kg/h, intravenously) contributed to reducing intraoperative opioids consumption and postoperative ache depth; it additionally had further benefits of inhibiting inflammatory response by lowering pro-inflammatory elements, equivalent to IL-6 and TNF-α, and sustaining immune perform.^10–12 Lidocaine can scale back cerebral infarction scopes inside 24 h after focal cerebral ischemia, confirming its brain-protection impact.¹³ Niiyama et al. demonstrated that lidocaine maintained adenosine triphosphate content material of hippocampal CA1 pyramidal neurons throughout and after ischemia by defending mitochondria, thus taking part in a neuroprotective position.¹⁴ Nevertheless, there are few research validating lidocaine’s results on restoration high quality and mind safety in sufferers after neurosurgery. On this research, we selected two typical mind injury-related elements, S100B and NSE, as our secondary outcomes, with a purpose to observe severity of central nervous system damage.^15,16

This randomized, double-blind, placebo-controlled medical trial was aimed toward investigating results of lidocaine on postoperative restoration high quality and its mind damage alleviation impact in supratentorial tumor resection. We hypothesized that systemic lidocaine would first, considerably enhance postoperative restoration high quality and second, that the development of postoperative restoration high quality would correlate with stress alleviation, inflammatory response discount, and mind damage alleviation impact.

Supplies and Strategies

This research was a single-center, potential, randomized, assessor-blinded, placebo-controlled medical trial between 1 November 2020 and 30 June 2021, permitted by the Ethics Committee of the Affiliated Hospital of Xuzhou Medical College and registered within the Chinese language Scientific Trial Heart (ChiCTR2000040209). Our analysis complied with the Declaration of Helsinki and adopted tips of CONSORT. Written knowledgeable consents have been obtained from all sufferers or household licensed earlier than enrollment.

Sufferers

Sixty sufferers (29 with gliomas and 31 with meningiomas) scheduled for supratentorial tumor resection with common anesthesia have been included, with age over 18, American Society of Anesthesiologists (ASA) bodily standing II–III, and 15 factors on the preoperative Glasgow Coma Rating. The exclusion standards included: metastatic supratentorial tumor; preoperative radiotherapy or chemotherapy; a historical past of craniotomy tumor resection; preoperative utilization of anti-inflammatory brokers or analgesics; recognized lidocaine intolerance; allergic reactions to any medication used on this research; irregular liver or kidney perform; extreme cardiopulmonary failure; involvement in different native anaesthetic interventions; low physique weight (<40 kg); with quick (<2 h) or lengthy (>6 h) surgical procedure length; and refusing to signal written knowledgeable consent. Sufferers with extreme hemodynamic disturbances or different life-threatening issues through the operation, or these transferred to the intensive care unit (ICU) after surgical procedure, have been eradicated.

Randomization and Blinding

Sixty sufferers have been randomly assigned to the lidocaine group (Group L) and the management group (Group C) in a 1:1 ratio by a computer-generated random sequence. Group numbers have been randomly saved in a closed envelope, and experimental medication have been ready by nurses who didn’t take part within the anesthesia operation after getting into the working room. Docs and different personnel concerned in anesthesia administration didn’t know concerning the grouping.

Research Intervention

All sufferers underwent fasting and water abstaining to organize for surgical procedure. After getting into the scheduled working room, peripheral venous entry was routinely opened, and radial artery puncture (after Allen check was confirmed to be damaging; in any other case non-invasive blood stress monitoring could be chosen) was accomplished. Then, blood stress, coronary heart fee (HR), electrocardiogram (ECG), pulse oxygen saturation (SpO₂), end-expiratory CO₂ (P_ETCO₂), and bispectral index (BIS) have been monitored. Anesthesia induction was carried out after pure oxygen inhalation practically amounting to five min: midazolam 0.05 mg/kg, sufentanil 0.5 μg/kg, etomidate 0.3 mg/kg, and rocuronium 0.6–1.0 mg/kg. Earlier than induction, sufferers in group L got 1.5 mg/kg lidocaine (iv.) inside 10 min (≤100 mg), adopted by 2.0 mg/kg/h lidocaine (iv.) after intubation till the top of surgical procedure. In Group C, sufferers obtained volume-matched regular saline loading dose and infusion as placebo. When BIS <50, endotracheal intubation was carried out with muscle leisure. Mechanical air flow parameters settings have been: tidal quantity (V_T) 6–8 mL/kg, respiratory fee (RR) 12–16 beats/min, the ratio of inspiratory and exhalation time (I:E) 1:1.5, P_ETCO₂ 30–35 mmHg. Anesthesia upkeep was: sevoflurane 1%, remifentanil 0.1–0.3 μg/kg/min, propofol 3–5 mg/kg/h, cis-atracurium 0.01 mg/kg/h, and BIS 40–60. Vasoactive brokers could be used when intraoperative blood stress and HR fluctuated dramatically (no less than 20% above or beneath baseline). All sufferers got 12.5 mg dolasetron (iv.) 15 min earlier than the top of surgical procedure. Anesthetics have been stopped after pores and skin closure.

After surgical procedure, sufferers have been transferred to postanesthesia care unit (PACU) for additional commentary. When extubation indications have been met, the endotracheal tube could be eliminated and the surgeon would carry out a neurological analysis.

Contemplating that postoperative ache might have an effect on bodily consolation, emotional state, and bodily independence, we adopted postoperative analgesia (diclofenac sodium) to take care of VAS <4, stopping the ache from affecting respiratory, sleep, or regular life. Remedial analgesia scheme within the ward: if VAS ≥4, a 75 mg diclofenac sodium hydrochloride sustained-release pill could be administered, and once more inside medical dose if essential.

Final result Assessments, Assortment of Blood Samples and Testing

The QoR-40 scale (the simplified Chinese language model by Myles et al.)² was used to document and consider postoperative restoration high quality by the identical skilled anesthesiologist at preoperative visits and postoperative follow-ups. World QoR-40 rating ranges from 40 to 200 factors (highest quality). It consists of 5 clinically related dimensions: bodily consolation (12 gadgets), emotional state (9 gadgets), bodily independence (5 gadgets), psychological help (7 gadgets), and ache (7 gadgets), every of which charges from 1 to five factors. Ache depth was evaluated with the VAS scores (0 = no ache, 10 = insufferable ache) at six time factors, specifically at postoperative hour (POH) 1, 2, 6, 12, 24 and 48. Sufferers have been assessed for PONV and consumption of diclofenac within the ward inside POH 24. Additional assessments included consumption of anesthetics and vasoactive medication, and incidences of hostile occasions throughout surgical procedure and extubation. Information on medical historical past, surgical procedure, the time to first defecation after surgical procedure, and size of hospital keep have been extracted from the medical data.

Blood samples have been collected from radial artery earlier than anesthesia induction (T₀) and on the finish of surgical procedure (T₄), subsequently saved at 4 °C in fridge. These samples have been centrifuged for 10 min at 3000 rpm to separate serum, which might be saved at −80 °C for subsequent testing. Plasma concentrations of S100B, NSE, IL-6 and TNF-α have been examined by an enzyme-linked immunosorbent assay (ELISA), utilizing commercially accessible kits (Shanghai Lanpai Biotechnology Co., Ltd, Shanghai, China).

Outcomes

Major outcomes have been QoR-40 scores on POD 1 and POD 2. Secondary outcomes have been as follows: QoR-40 scores on preoperative (Pre) day and POD 7; concentrations of pro-inflammatory elements (IL-6, TNF-α) and mind injury-related elements (S100B, NSE) assessed preoperatively (T₀) and on the finish of surgical procedure (T₄); imply artery stress (MAP) and HR have been recorded earlier than anesthesia induction (T₀), instantly after intubation (T₁), scalp incision (T₂), dura mater incision (T₃), finish of surgical procedure (T₄), and extubation (T₅); intraoperative consumption of sufentanil, remifentanil and propofol; incidences of coughing and agitation throughout extubation; neutrophil to lymphocyte ratio (NLR); incidence of 24 h PONV; time to first defecation; postoperative hospital keep; and ache depth.^15,16 VAS and Athens Insomnia Scale (AIS) have been used to judge ache depth and sleep high quality, respectively. Consumption of diclofenac within the ward and perioperative hostile occasions have been additionally recorded.

Statistical Evaluation

The pattern dimension was calculated with PASS (model 15, NCSS, LLC, Kaysville, UT, USA), based mostly on major final result measures, i.e. QoR-40 scores. The medical restoration high quality enchancment was outlined as a leap of no less than 10 factors within the QoR-40 rating on the primary 7 days after surgical procedure.¹⁷ Based mostly on outcomes by Lee et al.,¹⁸ common QoR-40 scores on POD 1 between two teams had a distinction of 13. The estimated pattern dimension was 28 sufferers per group, with an influence of 80% and an α threat of 0.05. To compensate for potential lack of follow-up or rejection, a ten% drop-out could be thought-about. Lastly, 64 sufferers have been included in our research.

Shapiro–Wilk check was carried out for normality check, and Levene’s check was used for homogeneity of variance check. Usually distributed knowledge have been analysed by Scholar’s t-test, introduced as imply and commonplace deviation (SD). Non-normally distributed knowledge have been in contrast by Mann–Whitney U-test, introduced as median and inter-quartile vary (IQR). Incidences of coughing and agitation throughout extubation and PONV have been in contrast by Fisher’s precise check or chi-square check, displayed as quantity and share. Repeated measurement analyses of variance (ANOVA) have been carried out to match hemodynamic parameters at completely different time factors and QoR-40 scores on completely different days. Variables equivalent to age, weight, peak, consumption of propofol and remifentanil, length of surgical procedure and anesthesia, pulmonary an infection, the VAS rating, utilization of colloidal resolution and crystalloid resolution, urine and bleeding quantity, AIS, and NLR have been included within the univariate regression evaluation. Components with P <0.2, the univariate linear regression evaluation recognized, and different variables that could be statistically vital, equivalent to consumption of propofol and remifentanil, have been included within the subsequent multivariate linear regression evaluation. All statistical analyses have been carried out utilizing IBM SPSS Statistics (Model 26, IBM SPSS, Chicago, IL, USA) and GraphPad Prism (Model 9, GraphPad Software program, La Jolla, CA, USA).

Outcomes

Affected person Traits

In the course of the interval of recruitment, a complete of 84 sufferers who have been scheduled for supratentorial tumor resection beneath elective common anesthesia have been screened from the Affiliated Hospital of Xuzhou Medical College. Fourteen members have been subsequently excluded for not satisfying the inclusion standards or refusing to take part. Thus, 70 people have been finally randomized into Group L or Group C. After randomization, 3 sufferers have been excluded: 2 for cancellation of the operation as a result of systolic blood stress exceeding 200 mmHg, and 1 for cancellation of the operation as a result of severely troublesome airway. Seven sufferers have been excluded after follow-up: 3 for transferring to ICU after surgical procedure, and 4 for postoperative pathology displaying non-tumor. Sixty sufferers lastly accomplished our research (Figure 1): 30 sufferers have been allotted to the lidocaine group, and 30 sufferers have been allotted to the traditional saline group. Eligible sufferers have been enrolled consecutively from 1 November 2020 to 30 June 2021, and there have been no vital variations in baseline traits between two teams (Table 1).

Research Endpoints

World QoR-40 scores and their 5 dimensions on Pre have been comparable within the two teams (Figure 2). In contrast with Pre, international QoR-40 scores, in addition to bodily consolation scores, emotional state scores, bodily independence scores, and ache scores had decreased (P <0.05) on POD 1 and POD 2; psychological help scores, on POD 1 in group C and on POD 2 in group L, had decreased (P <0.05); international QoR-40 scores, bodily consolation scores, and bodily independence scores on POD 7, in addition to ache scores in group C, had additionally considerably declined; whereas psychological help scores had considerably elevated (P <0.05).

The outcomes of univariate linear regression evaluation and multivariate linear regression evaluation of worldwide restoration high quality on POD 1 are proven in Table 1A and 1B, within the Supplementary 1. Utilization of intraoperative fluids had no distinction considerably between two teams (Table 2A, within the Supplementary 2). Incidences and grades of coughing and sedation have been decrease in group L than in group C (Table 3A, within the Supplementary 3).

Dialogue

The outcomes of our research confirmed that sufferers with systemic infusion of lidocaine throughout supratentorial tumor resection had increased postoperative restoration high quality than these within the regular saline group. In view of the decrease consumption of opioids, lighter depth of ache, much less incidence of PONV within the lidocaine group, in addition to decrease plasma ranges of pro-inflammatory (IL-6, TNF-α) and mind injury-related (S100B, NSE) elements, we might draw conclusions that inflammation-alleviating and analgesic properties of lidocaine participated within the enchancment of postoperative restoration high quality, in addition to its brain-injury alleviation impact.

The World Well being Group (WHO) outlined well being as: a state of good bodily, psychological and social actions. Within the twenty first century, together with the social construction of inhabitants getting older, the power to handle one’s personal discomfort and well being situations has been more and more valued, i.e. to answer varied environmental occasions.^8,19 In our research, scores of bodily consolation, emotional state and ache within the lidocaine group have been considerably improved on POD 1 and POD 2 in contrast with the matched group; and it was much like the research by Kim et al.²⁰ Nevertheless, lidocaine didn’t considerably enhance sufferers’ bodily independence scores and psychological help scores. Frailty is a troublesome downside that have to be confronted and handled within the strategy of postoperative restoration even affecting postoperative cognitive perform.^21,22 Donald et al. discovered that frailty, considerably associated to the bodily independence of aged sufferers after surgical procedure, delayed postoperative restoration course of and even led to dying.²³ Because of vast ranges of age in our research, the advantage of lidocaine on frailty in aged individuals stays to be additional confirmed. Multivariate regression evaluation confirmed that age was a major threat of restoration high quality after supratentorial tumor resection, which also needs to be paid extra consideration within the getting older society. On the identical time, it’s essential for clinicians to provide extra humanistic care, assist to enhance sufferers’ psychological high quality and provide extra social help, in order to reinforce a way of happiness and promote postoperative restoration.²⁴

When put into medical observe for the primary time, lidocaine was recognized for its potential to dam sodium ion channels, as a neighborhood anesthetic. An growing variety of research proved utilization of lidocaine throughout common anesthesia contributes to lowering consumption of propofol and remifentanil, which was additionally confirmed in our research.^12,25,26 This phenomenon might be defined by the truth that lidocaine shares sure widespread pathways (equivalent to blocking sodium ion channels) with propofol and remifentanil, in points of analgesic mechanisms.²⁷ Given the complexity of ache mechanisms, these pathways stay to be explored with additional randomized managed trials (RCTs) and confirmed by extra high-level basic experiments, with extra anesthesiologists’ efforts. Corcoran et al. discovered that propofol alleviated the stress response from surgical procedure by inhibiting the inflammatory response.²⁸ An attention-grabbing phenomenon present in our research was that, with intraoperative infusion of lidocaine, the propofol consumption lowered whereas inflammatory elements’ ranges considerably declined. A number of potential interpretations concerned have been as follows: (1) Anesthetic mechanisms of lidocaine and propofol weren’t fully overlapping; (2) lidocaine had a protecting impact on endothelial cells, however extreme infusion of propofol might destroy endothelial cells, which consequently weakened the anti-inflammatory impact of propofol by damaging the immune system; (3) lidocaine itself had an impact of inhibiting inflammatory response.^10,25,29,30

Lidocaine promotes postoperative restoration by ameliorating analgesic impact.^31,32 It was apparent that increased ache scores in our research considerably lowered postoperative restoration high quality, particularly POH 12 and POH 24; and this was according to the research by Licina et al.³³ Ache not solely causes short-term or long-term fluctuations in hemodynamics, but in addition delays mind perform returning to regular ranges, resulting in postoperative cognitive dysfunction or irregular psychological exercise; afterwards it slows down the postoperative restoration course of.^34,35 The previous was revealed by decrease fluctuations of intraoperative hemodynamic parameters (equivalent to MAP and HR) and decrease utilization of vasoactive medication in our research; and the incidence and extent of agitation lowered considerably throughout extubation, suggesting that lidocaine performed a constructive position in postoperative mind perform restoration. Moreover, there was no vital distinction in peripheral fluid infusion between teams on this research. Contemplating indicators intently associated to tissue perfusion weren’t monitored, it stays to be additional confirmed which technique, when it comes to sustaining steady blood stress and sustaining satisfactory tissue perfusion, was extra useful.

The surgical procedure, as one stressor, will inevitably stimulate the neuroendocrine system and the inflammatory immune response, hindering postoperative restoration.³⁶ Nevertheless, controlling intraoperative stress responses helps to enhance postoperative restoration high quality.³⁷ On this research, inflammatory and mind injury-related elements have been considerably elevated in contrast with these earlier than anesthesia induction. Nevertheless, lidocaine considerably lowered inflammatory elements ranges compared to regular saline, offering the proof that it mitigated the inflammatory response, and accelerated fairly than fully reversed the mind harm that originated from anaesthetic and operative stresses. We might speculate that the irritation alleviation impact of lidocaine is one in all its routes to enhance postoperative restoration high quality and performs a constructive position in mind safety. As well as, Tu et al. discovered that controlling ranges of inflammatory elements might additionally contribute to cognitive perform restoration, which additional confirmed the profit to mind of lidocaine.³⁸

PONV is among the advanced and vital issues in anesthesia observe. It’s well-known that opioids, largely belonging to μ-, δ- or κ-receptor agonists, can instantly activate the emetic chemoreceptor set off zone (CTZ) positioned within the medulla oblongata, evoking nausea and vomiting; and this impact is correlated with utilization quantity of opioids.³⁹ Echevarria et al. discovered that, in kids, there was no correlation between discount of opioid consumption and PONV.⁴⁰ Thus, it might be predicted that age was an vital threat issue for PONV. On this research, lidocaine might speed up gastrointestinal perform restoration and scale back the incidence of PONV primarily by way of lowering consumption of opioid medication and bettering analgesic impact. As well as, in sorts of surgical procedure equivalent to neurosurgery, the stress response derived from anaesthetic and surgical operations, and ache occasions are additionally threat elements for PONV.⁴¹ It’s nonetheless essential and difficult for anesthesiologists to actively take part in multidisciplinary cooperation and promote completion of high-quality enhanced restoration after surgical procedure.⁴²

Intravenous lidocaine might trigger varied hostile results, together with tongue and lip numbness, metallic style within the mouth, dizziness, convulsions, and arrhythmias. Exclusion standards have been strictly adopted to make sure probably in danger people have been excluded as fully as potential. If the P-R interval extended, the QRS wave widened in ECG, or arrhythmia occurred throughout lidocaine infusion, the trial could be cancelled. The widespread intravenous lidocaine infusion regimens in medical observe have been 100 mg or 1.5–2.0 mg/kg initially, and 1–3 mg/kg/h subsequently.⁴³ Carabalona et al. additionally discovered that the median serum focus of lidocaine was 1.45 (0.98–1.88) µg/mL following a 1.5 mg/kg bolus and intravenous infusion at a fee of two.0 mg/kg/h, which didn’t attain poisonous concentrations (outlined as >5 µg/mL).⁴⁴ Due to this fact, the dose of lidocaine used on this research might be thought-about protected, by which the overall dose of lidocaine per particular person was usually distributed (529.3±145.8 mg), starting from 253.3 mg to 893.5 mg. On the identical time, we didn’t discover any hostile results attributing to lidocaine occurring on this research.

Our conclusions on this research have been obtained within the context of sure limitations. Firstly, lidocaine focus in plasma was not monitered. The dose of lidocaine administrated referred to earlier research.^43,45,46 Though poisonous results of lidocaine are simply acknowledged in acutely aware topics (in extra of 5 μg/mL in plasma), topics within the standing of common anesthesia want increased degree of lidocaine as much as 10 μg/mL in plasma when circulatory melancholy might be found. Fortunately, none had but to expertise persistent arrhythmia, convulsions or different hostile occasions originating from lidocaine in our research. Secondly, the restoration high quality on this research was solely assessed inside postoperative 7 days, and didn’t be continued follow-up for longer durations of time. The impact of intravenous lidocaine on long-term restoration requires extra medical trials to be carried out. Thirdly, earlier research have explored completely different infusion durations and charges of lidocaine administration, primarily starting from the top of the surgical procedure to 48 h later and from 1.0 mg/kg/h to three.0 mg/kg/h, respectively, however we solely adopted one kind of dose of lidocaine and infused intravenously lasting as much as the top of surgical procedure. Due to this fact, optimum dose of lidocaine on accelerating postoperative restoration high quality stays to be additional evaluated. Fourthly, a number of current research have reported the anti-tumor impact of lidocaine, whereas our research didn’t give attention to prognoses equivalent to progression-free survival, survival and mortality charges.^47,48 Additional research shall be wanted to discover this profit in sufferers after neurosurgery. Lastly, elevated S100B, as an indication of central nervous system damage, might additionally happen within the absence of mind damage. Though there was no statistical distinction within the distribution of surgical procedure sorts or surgical procedure length between the 2 teams in our research, S100B in plasma may be affected by a number of elements, equivalent to the quantity of train, diploma of muscle damage, hemolysis, and even measurement strategies.¹⁶ On the identical time, lidocaine might scale back ranges of inflammatory elements by assuaging ache, which might make the direct anti-inflammatory impact of lidocaine unclear. Due to this fact, additional management of those variables or additional research to cut back the confounding bias shall be essential.

Conclusion

Systemic lidocaine notably improved postoperative early restoration high quality after supratentorial tumor resection, with irritation and ache alleviated, and perioperative opioid consumption lowered. It additionally had a constructive mind damage alleviation impact in sufferers after neurosurgery. Contemplating there are few research validating its mind safety impact, additional research confirming the brain-protection mechanism of lidocaine are warranted.
