Abstract
BACKGROUND AND OBJECTIVES: Present clinical study was conducted to evaluate advantages of field block for inguinal hernia repair, with respect to duration and quality of analgesia, haemodynamic stability, and speed of recovery by using 1% lidocaine with adrenaline. METHODS: Study was conducted on 50 patients posted for elective inguinal hernia repair. Field block was instituted with 1% lidocaine with adrenaline with mean volume of 35.48 ml to block ilioinguinal, iliohypogastric, genital branch of genitofemoral nerve with subcutaneous infiltration. Patients were observed for duration and quality of analgesia. Haemodynamic stability with PR, systolic and diastolic BP. Post anaesthesia recovery was assessed by using “criteria for fast track eligibility for ambulatory anaesthesia” after the surgery. Duration of analgesia was assessed with subjective complaint of pain (duration of onset of analgesia till the subjective complaint of pain). RESULTS: In the present study, the quality of analgesia was excellent in 72% of cases, good in 16%, fair in 8% and poor in 4%. The mean duration of analgesia was 201.02 min (160 min to 280 min). All patients were haemodynamically stable throughout the surgery. Using fast tract eligibility criteria for recovery all the patient had a score of 12 at 0 min and all of them had score of > 12 at 15 min and 30 min and were ready to be shifted toward from the OR bypassing the post anaesthesia recovery room. CONCLUSION: Thus field block for inguinal hernia repair is a safe technique, that provides excellent quality and prolonged analgesia, with rapid recovery and minimal to nil complications.
