Abstract
Background / Aim: The concept of general balanced anaesthesia was devised in order to assure cardiovascular stability and fast post-anaesthesia recovery. This clinical trial was organised in order to investigate the parameters of cardiovascular function and emergence from anaesthesia in elective ear, nose and throat (ENT) surgery patients. Methods: A total of 40 ASA I and II patients of both sexes scheduled for elective ENT surgery were randomly divided into two equal groups. Both groups received a continuous IV infusion of glucose 5 % solution and in the esmolol group this infusion also contained esmolol. Esmolol infusion rate was 0.3 mg/kg/min during the first 5 min and thereafter 0.1 mg/kg/min. In critical phases of anaesthesia and operation (induction, intubation, first incision, surgical manipulations, wound suture, extubation), systolic and diastolic blood pressure were monitored. Recovery after anaesthesia was assessed based on times of eye opening on command, spontaneous eye opening and regaining of full orientation. Increases in cardiovascular parameters by 20 % of the baseline values or more were treated with IV boluses of fentanyl, alone or with droperidol and, if necessary, by adding isoflurane 0.5 % to the inhalational mixture. Consumption of drugs was recorded. Results: Esmolol assured stable values of cardiovascular parameters that were in most critical phases of anaesthesia and operation lower than in the control group. The duration of anaesthesia did not differ between the groups. In the esmolol group, lower consumption of fentanyl, droperidol and sevoflurane was registered. Patients in the esmolol group emerged from anaesthesia faster than patients in the control group. Conclusion: Continuous IV infusion of esmolol assures better cardiovascular stability, necessitates lower consumption of analgesics and anaesthetics and results in faster emergence from general anaesthesia in elective ENT surgery.

[PMID: 33873003 DOI: 10.1016/j.jclinane.2021.110287] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 04/05/2021] [Accepted: 04/06/2021] [Indexed: 11/24/2022]
Abstract
STUDY OBJECTIVE An uncontrolled adrenergic response during tracheal intubation may lead to life-threatening complications. Dexmedetomidine binds to α2-receptors and may attenuate this response. The primary aim of our meta-analysis is to investigate dexmedetomidine efficacy in attenuating sympathetic response to tracheal intubation, compared with placebo or no dexmedetomidine, in terms of heart rate and blood pressure at intubation. DESIGN Meta-analysis with meta-regression and trial sequential analysis. SETTING Systematic search from inception until December 1, 2020 in the following databases: Pubmed, Scopus, the Cochrane Central Register of Controlled Trials, EMBASE and Google Scholar. INTERVENTIONS All randomized controlled trials investigating intravenous dexmedetomidine as premedication in adult patients undergoing tracheal intubation were included in our study. Studies were included without any language or publication date restriction. A trial sequential analysis and a post-hoc meta-regression were performed on the main outcomes. MEASUREMENTS Hemodynamic parameters and heart rate at tracheal intubation, dose of anesthetic needed for induction of anesthesia, total anesthetic requirement throughout the operative procedure, postoperative pain and percentage of patients requiring analgesics at 24 postoperative hours, postoperative nausea and vomiting, intraoperative and postoperative bradycardia, hypotension, dizziness, shivering and/or respiratory depression. MAIN RESULTS Ninety-nine included studies randomized 6833 patients. During laryngoscopy, all hemodynamic parameters were significantly greater in the no dexmedetomidine group. In particular, in the dexmedetomidine group, systolic blood pressure differed by -21.8 mm Hg (95% CI -26.6 to -17.1, p-value < 0.001, I2 97%), mean arterial pressure by -12.8 mm Hg (95% CI -15.6 to -10.0, p-value < 0.001, I2 98%), and heart rate by -16.9 bpm (95% CI -19.8 to -13.9, p-value < 0.001, I2 98%). CONCLUSIONS Patients receiving premedication with dexmedetomidine for tracheal intubation, compared with no dexmedetomidine, have a lower blood pressure and heart rate, however, the risk of bradycardia and hypotension is relevant and its use during daily practice should be cautiously evaluated for each patient.

Abstract
Background/Aim: In surgery, and especially in the neurosurgical operations, maintenance of cardiovascular stability during and in the phase of the immediate postoperative recovery is of vital importance. The aim of this study was to investigate the effects of continuous esmolol infusion on the values of cardiovascular parameters and quality of the emergence from anaesthesia in neurosurgical patients. Methods: A total of 40 patients of both sexes scheduled for elective supratentorial surgery were randomly assigned to two groups. Esmolol group received intravenous (iv) infusion of esmolol dissolved in 5 % glucose solution (during the first 5 min at a rate of 0.3 mg/kg/min and thereafter at a rate of 0.1 mg/kg/min), while the ones from the control group received a 5 % glucose solution without esmolol at the same volume and rate. Cardiovascular parameters were registered at critical phases of anaesthesia and operation (induction, intubation, placement of Mayfield frame, craniotomy, skull closure, extubation). Recovery after anaesthesia was assessed based on times of eye opening on command, spontaneous eye opening and regaining of full orientation. Results: Values of systolic blood pressure and heart rate were significantly lower in the esmolol than in the control group of patients. Although the durations of anaesthesia did not differ, patients from the esmolol group required significantly less opioids and isoflurane and recovered after the anaesthesia significantly faster than the patients in the control group. Conclusion: Ultrashort-acting beta-adrenergic receptor antagonist esmolol, administered as a continuous iv infusion, assures better cardiovascular stability and smoother emergence from the balanced inhalation general anaesthesia than the control glucose infusion in elective neurosurgical patients.

Abstract
Background: The aim of this study was to compare the effects of dexmedetomidine, esmolol, and combination of both on control of sympathetic response to laryngoscopy and tracheal intubation in coronary artery disease patients. Material and Methods: A prospective, randomized, double-blinded clinical study included 90 patients scheduled for elective coronary artery bypass surgery. Patients were randomly allocated into three groups of 30 each: dexmedetomidine group (Group D) 1 μg/kg, esmolol group (Group E) 2 mg/kg, and group dexmedetomidine with esmolol (Group DE) 0.5 μg/kg of dexmedetomidine with 1 mg/kg of esmolol. Each drug was diluted with 0.9% normal saline to 20 ml volume and infused in 10 min before induction of anesthesia. Hemodynamic changes (heart rate [HR], arterial blood pressure, and pulmonary artery pressure) were compared at various time intervals as follows-baseline, after study drug, after induction, and 1, 3, and 5 min after intubation. Statistical analysis included analysis of variance, Chi-square, and Fisher's exact test. Results: In Group DE, there was no significant increase in HR at all-time intervals, and the HR was stable compared to Group D and Group E. Blood pressure values were comparable in all groups except in Group E at 5 min. The pulmonary arterial pressures were statistically less in DE group except at 3 and 5 min. Conclusions: The combination of dexmedetomidine and esmolol group has beneficial effect on HR and pulmonary arterial pressures but has no additional advantage with respect to arterial blood pressure when compared with dexmedetomidine and esmolol groups in patients undergoing elective coronary artery bypass grafting.

Abstract
BACKGROUND Randomized controlled trials (RCTs) have yielded conflicting results regarding the ability of beta-blockers to influence perioperative cardiovascular morbidity and mortality. Thus routine prescription of these drugs in an unselected population remains a controversial issue. A previous version of this review assessing the effectiveness of perioperative beta-blockers in cardiac and non-cardiac surgery was last published in 2018. The previous review has now been split into two reviews according to type of surgery. This is an update, and assesses the evidence in non-cardiac surgery only. OBJECTIVES To assess the effectiveness of perioperatively administered beta-blockers for the prevention of surgery-related mortality and morbidity in adults undergoing non-cardiac surgery. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, Biosis Previews and Conference Proceedings Citation Index-Science on 28 June 2019. We searched clinical trials registers and grey literature, and conducted backward- and forward-citation searching of relevant articles. SELECTION CRITERIA We included RCTs and quasi-randomized studies comparing beta-blockers with a control (placebo or standard care) administered during the perioperative period to adults undergoing non-cardiac surgery. If studies included surgery with different types of anaesthesia, we included them if 70% participants, or at least 100 participants, received general anaesthesia. We excluded studies in which all participants in the standard care control group were given a pharmacological agent that was not given to participants in the intervention group, studies in which all participants in the control group were given a beta-blocker, and studies in which beta-blockers were given with an additional agent (e.g. magnesium). We excluded studies that did not measure or report review outcomes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion, extracted data, and assessed risks of bias. We assessed the certainty of evidence with GRADE. MAIN RESULTS We included 83 RCTs with 14,967 participants; we found no quasi-randomized studies. All participants were undergoing non-cardiac surgery, and types of surgery ranged from low to high risk. Types of beta-blockers were: propranolol, metoprolol, esmolol, landiolol, nadolol, atenolol, labetalol, oxprenolol, and pindolol. In nine studies, beta-blockers were titrated according to heart rate or blood pressure. Duration of administration varied between studies, as did the time at which drugs were administered; in most studies, it was intraoperatively, but in 18 studies it was before surgery, in six postoperatively, one multi-arm study included groups of different timings, and one study did not report timing of drug administration. Overall, we found that more than half of the studies did not sufficiently report methods used for randomization. All studies in which the control was standard care were at high risk of performance bias because of the open-label study design. Only two studies were prospectively registered with clinical trials registers, which limited the assessment of reporting bias. In six studies, participants in the control group were given beta-blockers as rescue therapy during the study period.The evidence for all-cause mortality at 30 days was uncertain; based on the risk of death in the control group of 25 per 1000, the effect with beta-blockers was between two fewer and 13 more per 1000 (risk ratio (RR) 1.17, 95% confidence interval (CI) 0.89 to 1.54; 16 studies, 11,446 participants; low-certainty evidence). Beta-blockers may reduce the incidence of myocardial infarction by 13 fewer incidences per 1000 (RR 0.72, 95% CI 0.60 to 0.87; 12 studies, 10,520 participants; low-certainty evidence). We found no evidence of a difference in cerebrovascular events (RR 1.65, 95% CI 0.97 to 2.81; 6 studies, 9460 participants; low-certainty evidence), or in ventricular arrhythmias (RR 0.72, 95% CI 0.35 to 1.47; 5 studies, 476 participants; very low-certainty evidence). Beta-blockers may reduce atrial fibrillation or flutter by 26 fewer incidences per 1000 (RR 0.41, 95% CI 0.21 to 0.79; 9 studies, 9080 participants; low-certainty evidence). However, beta-blockers may increase bradycardia by 55 more incidences per 1000 (RR 2.49, 95% CI 1.74 to 3.56; 49 studies, 12,239 participants; low-certainty evidence), and hypotension by 44 more per 1000 (RR 1.40, 95% CI 1.29 to 1.51; 49 studies, 12,304 participants; moderate-certainty evidence).We downgraded the certainty of the evidence owing to study limitations; some studies had high risks of bias, and the effects were sometimes altered when we excluded studies with a standard care control group (including only placebo-controlled trials showed an increase in early mortality and cerebrovascular events with beta-blockers). We also downgraded for inconsistency; one large, well-conducted, international study found a reduction in myocardial infarction, and an increase in cerebrovascular events and all-cause mortality, when beta-blockers were used, but other studies showed no evidence of a difference. We could not explain the reason for the inconsistency in the evidence for ventricular arrhythmias, and we also downgraded this outcome for imprecision because we found few studies with few participants. AUTHORS' CONCLUSIONS The evidence for early all-cause mortality with perioperative beta-blockers was uncertain. We found no evidence of a difference in cerebrovascular events or ventricular arrhythmias, and the certainty of the evidence for these outcomes was low and very low. We found low-certainty evidence that beta-blockers may reduce atrial fibrillation and myocardial infarctions. However, beta-blockers may increase bradycardia (low-certainty evidence) and probably increase hypotension (moderate-certainty evidence). Further evidence from large placebo-controlled trials is likely to increase the certainty of these findings, and we recommend the assessment of impact on quality of life. We found 18 studies awaiting classification; inclusion of these studies in future updates may also increase the certainty of the evidence.

Abstract
Context: Laryngoscopy and endotracheal intubation lead to strong sympathetic response which may precipitate arrhythmias, myocardial ischemia and cerebrovascular accidents in patients with preexisting cardiovascular disease. Aims: This study was aimed to compare the effect of dexmedetomidine and esmolol on hemodynamic response to laryngoscopy and endotracheal intubation in patients undergoing elective surgery under general anesthesia. Settings and Design: This was a prospective, randomized controlled double-blinded study. Materials and Methods: A total of ninety patients were selected and randomized into three groups of thirty patients each: Group C received infusion of 20 mL 0.9% normal saline (NS) over 10 min, Group D received infusion of dexmedetomidine 1 μg/kg diluted in 20 mL NS over 10 min, and Group E received infusion of esmolol 1.5 mg/kg diluted in 20 mL NS over 10 min. Three minutes after the completion of infusion, patients were induced with general anesthesia. Baseline parameters such as heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), and rate pressure product (RPP) were recorded before administration of study drugs and at 1, 3, 5, 7, and 10 min after intubation. Statistical Analysis Used: One-way ANOVA was used for comparison among the groups and unpaired t-test was used for comparison within the groups along with Tukey's test for post test analysis. Results: Mean HR, SBP, DBP, MAP, and RPP values remained significantly lower in Group D than that of Group C and Group E at all time intervals up to 10 min after intubation. Conclusions: Both dexmedetomidine and esmolol suppressed the hemodynamic response to intubation when compared to control group, but dexmedetomidine is more effective than esmolol in maintaining hemodynamic stability following laryngoscopy and intubation.

Abstract
BACKGROUND AND AIMS Laryngoscopy and endotracheal intubation are associated with reflex sympathetic stimulation, known as pressor response and can cause major complications. We compared the attenuating effect of time-tested lignocaine versus clonidine on the hemodynamic response to laryngoscopy and intubation in neurosurgical cases. DESIGN A prospective, randomized, comparative, double-blind study with a sample size of sixty patients. METHODS Sixty patients undergoing elective neurosurgery were randomly allocated into one of the two groups: Group L (n = 30) received lignocaine 1.5 mg/kg intravenous (i.v.) before induction and Group C (n = 30) received clonidine 2 μg/kg i.v. before induction. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were recorded at baseline, after drug, after induction and 1, 2, 3,5,10, and 15 min after intubation. STATISTICAL ANALYSIS Statistical software, namely, SPSS, version 15.0 by SPSS Inc., Chicago, USA was used for the analysis of data with Chi-square test to compare intergroup hemodynamic parameters. RESULTS Mean HR remained above baseline at all times after intubation in lignocaine group but decreased at 2 min after intubation and remained below baseline at all times in the clonidine group. SBP, DBP, and MAP all increased above baseline at 1 min after intubation in lignocaine group, and decreased below baseline at 2 min after intubation, whereas in the clonidine group they all decreased below baseline after drug administration and remained below baseline at all times. Therefore, clonidine is very effective in attenuating pressor responses and this difference between the groups is statistically very significant with P < 0.001. CONCLUSION Clonidine is more effective than lignocaine for attenuating the pressor responses to laryngoscopy and endotracheal intubation in neurosurgical cases.

Abstract
BACKGROUND Direct layngoscopy and endotracheal intubation is a noxious stimuli and induces sympathomimetic responses. Although well tolerated in healthy subjects, it may impose life threatening arrhythmias, left ventricular failure or rupture of cerebral aneurysm in susceptible patients. Esmolol, Labetalol and Lignocaine attenuate these responses but are associated with side effects of bradycardia, hypotension etc. In lower doses, chances of these side effects are comparatively low. So we designed this prospective clinical trial to assess the efficacy of intravenous esmolol, labetalol and lignocaine in low doses for attenuation of sympathomimetic responses to endotracheal intubation. MATERIALS AND METHODS Seventy-five consenting patients of ASA physical status I or II of age range 20 to 60 years, scheduled for different general surgical procedures were randomly assigned to one of the three groups; group ES, group LB and group LG. Participants of group ES, group LB and group LG was given esmolol HCL 0.5 mg/Kg, labetalol HCL 0.25 mg/kg and lignocaine HCL 1 mg/Kg body weight respectively. Outcome variables were HR, SBP, DBP, MAP and RPP. These variables were recorded just after intubation and thereafter at 1,3,5, 7 and 10 minutes of intubation. RESULTS There was no statistically significant difference regarding the demographic characteristics of the groups. Heart rate and systolic blood pressure was lower throughout the study period in labetalol group. But the values of study parameters were always higher than the baseline in esmolol and lignocaine group. Values of mean arterial pressure was slightly higher in labetalol group but it was much higher in two other groups throughout the study period. Diastolic blood pressure was higher in all the groups. Values of rate pressure product was higher during intubation and at 1minute after intubation in labetalol group but thereafter it was always lower than baseline values. CONCLUSION Labetalol 0.25 mg Kg-1 is an effective and safe drug to be used for attenuation of sympathomimetic responses to endotracheal intubation. Esmolol 0.5 mg Kg-1 and lignocaine 1 mg Kg-1 are also effective to some extent and are safe.

OBJECTIVE To study the clinical effect and mechanism of action of esmolol in the treatment of severe hand, foot, and mouth disease (HFMD). METHODS A prospective randomized controlled trial was performed. A total of 102 children with severe HFMD were enrolled in the study and were randomly divided into conventional treatment and esmolol treatment groups (n=51 each). The children in the conventional treatment group were given conventional treatment according to the guidelines for the diagnosis and treatment of HFMD. Those in the esmolol treatment group were given esmolol in addition to the conventional treatment. The heart rate (HR), systolic blood pressure (SBP), and respiratory rate (RR) were continuously monitored for all children. Blood samples were collected from all children before treatment and 1, 3, and 5 days after treatment to measure the levels of norepinephrine (NE), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and nuclear factor-kappa B (NF-κB) p65 in mononuclear cells. Serum levels of myocardial enzymes and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured before treatment and after 5 days of treatment. RESULTS There were no significant differences in HR, SBP, RR, NE, TNF-α, IL-6, NF-κB p65, serum myocardial enzymes, and NT-proBNP before treatment between the conventional treatment and esmolol treatment groups. Both groups had significant reductions in these parameters at each time point (P<0.05). Compared with the conventional treatment group, the esmolol treatment group had significant improvements in the above parameters after 1 and 3 days of treatment (P<0.05). After 5 days of treatment, the esmolol treatment group had significant improvements in serum levels of myocardial enzymes and NT-proBNP compared with the conventional treatment group (P<0.05). CONCLUSIONS Early application of esmolol can effectively stabilize the vital signs of the children with severe HFMD. Its mechanism of action may be related to reducing serum catecholamine concentration, alleviating myocardial damage, improving cardiac function, and reducing inflammatory response.

Abstract
Background: Esmolol has an established role in attenuation of hemodynamic response to laryngoscopy and endotracheal intubation. We studied the effect of dexmedetomidine compared to that of esmolol in this study. Aim: To study the role of dexmedetomidine in attenuation of hemodynamic response to laryngoscopy and oral endotracheal intubation compared to that of esmolol hydrochloride in patients posted for elective surgery under general anesthesia. Study Design: Prospective randomized study double-dummy blinding method. Materials and Methods: A total of 60 American Society of Anesthesiologists I patients, aged 18–60 years randomly divided into two groups; Group A patients received dexmedetomidine 1 mcg/kg diluted in 50 ml with normal saline and infused over 10 min before induction and also 20 ml of normal saline intravenous (IV) 2 min before endotracheal intubation. Group B patients received 50 ml IV infusion of normal saline over 10 min before induction and IV bolus of esmolol 0.5 mg/kg diluted in 20 ml with normal saline given 2 min before intubation. Standard induction technique followed. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) were recorded just before induction and after intubation at 1 min, 3 min, and 5 min after intubation. Statistical Analysis: Independent samples t-test and repeated measures of analysis of variance. Results: Dexmedetomidine group showed statistically significant reduction in all the study parameters at all study time intervals following intubation. While esmolol group showed significant attenuation of HR, SBP, and MAP following intubation but failed to produce significant reduction in DBP. Conclusion: Dexmedetomidine is more effective in attenuating the hemodynamic response to oral endotracheal intubation compared to that of esmolol hydrochloride.

Abstract
Background: The advent of laparoscopic surgeries has proved to be beneficial for both patient and surgeon although increased morbidity may result from hemodynamic changes associated with laryngoscopy, intubation, and pneumoperitoneum (PNP). Aim: The present study was prospective, randomized, double-blind conducted to evaluate the efficacy of dexmdetomidine and fentanyl in attenuation of pressor responses to laryngoscopy, intubation, and PNP in laparoscopic cholecystectomy (LC). Materials and Methods: A total of 60 patients of 18–65 years, American Society of Anaesthesiologists Class I/II of either sex for elective LC, were included. The patients were divided into two groups of 30 patients each. Group I received dexmedetomidine and Group II Fentanyl loading 1 μg/kg over 15 min followed by maintenance 0.2 μg/kg/h throughout the PNP. Measurements: Heart rate (HR), systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure (MAP) were recorded preoperatively, 15 min after infusion of study drug, 1 min after induction, 1 min after intubation, throughout the PNP, end of surgery, and until 60 min in postoperative period. Sedation score, visual analog scale score along with modified Alderete score applied in postanesthesia care unit. Results: Control of HR and MAP in Group I was better than in Group II during laryngoscopy, intubation and PNP. There was also smooth extubation, less sedation and better control of pain in Group I than in Group II. Conclusion: The present study demonstrates the benefits of dexmedetomidine over fentanyl in hemodynamic stability and analgesic quality in LC. Thus, it is establishing its utility over for attenuation of pressor response.
