Abstract

BACKGROUND AND AIMS: Modified Radical Mastectomy (MRM) is the commonly used surgical procedure for operable breast cancer, which involves extensive tissue dissection. Therefore, wound instillation with local anaesthetic may provide better postoperative analgesia than infiltration along the line of incision. We hypothesised that instillation of bupivacaine through chest and axillary drains into the wound may provide postoperative analgesia.

METHODS: In this prospective randomised controlled study 60 patients aged 45-60 years were divided into three groups. All patients were administered general anaesthesia. At the end of the surgical procedure, axillary and chest wall drains were placed before closure. Group C was the control with no instillation; Group S received 40 ml normal saline, 20 ml through each drain; and Group B received 40 ml of 0.25% bupivacaine and the drains were clamped for 10 min. After extubation, pain score for both static and dynamic pain was evaluated using visual analog scale and then 4(th) hourly till 24 h. Rescue analgesia was injection tramadol, if the pain score exceeds 4. Statistical analysis was performed using SPSS version 13.

RESULTS: There was a significant difference in the cumulative analgesic requirement and the number of analgesic demands between the groups (P: 0.000). The mean duration of analgesia in the bupivacaine group was 14.6 h, 10.3 in the saline group and 4.3 h in the control group.

CONCLUSION: Wound instillation with local anaesthetics is a simple and effective means of providing good analgesia without any major side-effects.

Keywords: Local anaesthetic; mastectomy; postoperative pain; wound instillation
