Drug Utilization Pattern of Anesthetics in a Tertiary care Hospital

Abstract

Background: Anesthesia means ‘loss of sensation’. Medications that cause anesthesia are called anesthetics. Anesthetics are used during tests and surgical operations to induce sleep, which prevents pain and discomfort and enables a wide range of medical procedures to be performed. Objective: To evaluate drug utilization pattern of anesthetics in a tertiary care teaching hospital. Materials and methods: The study was a Simple Prospective Observational study which was carried out for a period of six months. The patients were collected based on the inclusion and exclusion criteria.  A total of 125 cases were collected in which anesthetics were administered for surgical procedures. In this study, the type of anesthetics mostly administered to patients whether single or in combination was evaluated.  The gender, age of the patient, type of anesthetic and type of surgery performed were reported. The results were analyzed and evaluated.  Results: A total of 125 anesthetic cases were collected. Of these, 51 (41.8%) were of General anesthesia and 74 (59.2%) were of Local anesthesia. Among the 125 cases, males were 67 (56.8%) and females were 58 (46.4%) underwent surgery which involved anesthetic usage. Among General anesthetics, Propofol (P), Nitrous Oxide (N), Isoflurane (I), Midazolam (M), Suxamethonium chloride (S), Vecuronium (V) were used in combination. PNIM was used in 23 (18.4%) cases. PNIS 16 (12.8%) of cases, PNIMV 12 (9.6%). Among Local Anesthestics, Bupivacaine (B), Lignocaine (L), Xylocaine (X) were used in combination or single. BLA 9 (7.2%) cases, BMXA 10 (8%) cases, Bupivacaine 35 (28%), Lignocaine 7 (5.6%) and Xylocaine 13 (10.4%). Based on surgery, the most commonly performed surgery was Hemorrhoidectomy 28 (22.4%). Conclusion: Evaluation of utilization of anesthetics and implementation of effective strategies can greatly aid in improving the quality use of anesthetics.
