CHOLECYSTECTOMY; Comparison of total intravenous anesthesia with volatile induction maintenance anesthesia at a tertiary care hospital in Karachi Pakistan

摘要

Objectives: The aim of our study which is to compare total intravenousanesthesia with target controlled infusion using the drugs Propofol and remifenatnil with thetechniques of volatile induction maintenance anesthesia using sevoflurane and sufentanil inpatients undergoing laparoscopic cholecystectomy procedure, at a tertiary care hospital inKarachi, Pakistan. Study Design: The type of study is a randomized control trial, conductedfor a period of 8 months Period: from June 2015 to January 2016 Setting: at a tertiary carehospital in Karachi Pakistan. Method: The patient population consisted of n=100 patientsbelonging to the ASA class I and II and undergoing laparoscopic cholecystectomy procedure atour institute. The patients were divided into two groups group A consisted of all those patientswho underwent total intravenous anesthesia and group B consisted of patients who underwentvolatile induction maintenance anesthesia. Appropriate blinding measures were taken for thosewho were involved in the post-operative care of the patients, and the patients themselves. Duringthe procedure routine monitoring was done, data was recorded in a pre-designed proforma.Patients were analyzed in the post-operative period for side effects and pain levels. Statisticalanalysis was done using SPSS version 23, a p value of less than 0.05 was considered to bestatistically significant. Results: The patient population consisted of n= 100 patients dividedinto two groups. No statistically significant difference was found between the demographicvariables of the patients of both groups (age, weight, baseline values of blood pressure, heartrate, time duration of surgery and anesthesia). The time for the loss of corneal reflex was longerin the group A (109 +/- 90) as compared to group B (45 +/- 10) having a p value of less than0.001. However the time for opening of the eyes and the duration of post anesthesia care unitwas shorter in group A (420 +/- 130 seconds for eye opening and 45 +/- 15 min for PACU) andin group B (484 +/- 116 seconds for eye opening and 53 +/- 25 mins for PACU) having p valuesof 0.006 (eye opening) and 0.017 (PACU) respectively. In group A n= 44 (88%) of the patientsrequired rescue analgesia, and in group B n= 36 (72%) of the patients required it, having a pvalue of 0.013 respectively. The need for the use of ephedrine and atropine in the pre and portoperative period was similar in both the groups. Conclusion: According to the results of ourstudy we found that each method of anesthesia has its own advantages and disadvantagesand the anesthetist present should weigh the risks and benefits for each patient individually,and use the most beneficial method of administration of anesthesia in the patient undergoinglaparoscopic cholecystectomy procedure, accordingly.
