چکیده

BACKGROUND Lumbar spine surgery is associated with hemodynamic variations at intubation, change of position, and skin incision. A balanced anesthesia with multimodal analgesia (MMA) is necessary to attenuate these changes. AIM To assess the relative effectiveness of preemptive MMA compared with the conventional analgesic regime in suppressing the hemodynamic response to endotracheal intubation, prone positioning, and skin incision. SETTINGS AND DESIGN A randomized, prospective study involving 42 patients belonging to the American Society of Anesthesiologists Physical Status 1 and II scheduled to undergo elective lumbar spine surgery were allocated into two groups of 21 each. MATERIALS AND METHODS Forty-two patients were randomly allocated into Groups A and B. Group A (study group) received diclofenac, paracetamol, clonidine, and bupivacaine with adrenaline skin infiltration and Group B (control group) injection paracetamol and saline with adrenaline skin infiltration. STATISTICAL ANALYSIS USED Hemodynamic parameters (heart rate [HR], systolic blood pressure [SBP], diastolic blood pressure [DBP], and mean arterial pressure [MAP]) between the groups following intubation, prone position, and skin incision were noted and compared using repeated measure analysis of variance. One sample t-test was used to compare the standard mean concentration with the means of the study and control groups. P < 5% being considered statistically significant. RESULTS In the study group, HR, SBP, DBP, and MAP were lower at intubation and change of position as compared to the control group and were statistically significant. CONCLUSION Preemptive MMA with balanced anesthesia is effective in attenuating the hemodynamic responses to multiple noxious stimuli during lumbar spine surgery.

Evaluation of Mexiletine Effect on Bispectral Index Changes and Hemodynamic Responses to Endotracheal Intubation and During General Anesthesia

  Background &Objective: Plaryngoscopy and tracheal intubation increase not only blood pressure and heart rate but also Bispectral Index (BIS) of the patients. In this study, hemodynamic and BIS changes were surveyed after tracheal intubation and during general anesthesia followed by mexiletine prescription . Materials & Methods: In this study, 50 patients aged between 20 and 60 who were ca...

Effects of epidural and intravenous buprenorphine on halothane minimum alveolar anesthetic concentration and hemodynamic responses.

There is limited information regarding the effects of epidural or intravenous (i.v.) buprenorphine on minimum alveolar anesthetic concentration (MAC) of volatile anesthetic and hemodynamic responses to tracheal intubation and surgical incision. This study was conducted to find the effects of i.v. and epidural buprenorphine required for postoperative pain relief on halothane MAC and hemodynamic ...

Comparison of hemodynamic changes in patients using conventional laryngoscopy and video laryngoscope in surgery

Introduction: One of the complications of laryngoscopy and endotracheal intubation is sympathetic stimulation with hemodynamic changes that are always tried to be avoided by anesthesiologists. The aim of this study is to review and compare hemodynamic changes caused by both conventional and video laryngoscopy. Methods: In this clinical trial performed in 2015 in the Birjand-based Imam Reza Hosp...
