Abstract
BACKGROUND & PURPOSE: The recent advances in anaesthesia and analgesia have significantly improved the early recovery and effective post-operative pain control in day care surgery e.g. shoulder arthroscopic procedures. Adequate analgesia improves the early rehabilitation for a better outcome. We prospectively evaluated the post-operative pain relief following the two methods of analgesia i.e. regional Inter-scalene block (ISB) vs Intra-articular (IA) injection using 0.5% Chirocaine in various therapeutic arthroscopic shoulder procedures. METHODS: A prospective comparative study was performed on a group of 105 patients (ASA grade I or II) who underwent the following procedures at two different hospitals: diagnostic arthroscopy, subacromial decompression (SAD) alone, SAD in combination with mini open cuff repairs or distal clavicle excision, anterior stabilization (Bankart's repair) and inferior capsular shift. A successful Inter-scalene block (0.5% Chirocaine-30mls) preceded the general anaesthesia (Group 1-52 patients). Local intra-articular infiltration (0.5% Chirocaine - 20 mls) was given postoperatively (Group 2-53 patients). Post operatively visual analogue scores (VAS) from 0 (no pain) to 10 (severe pain) were assessed in post-anaesthesia care unit (PACU), at 4hrs, at 24hrs and at 48 h. The amount of morphine consumption for the first 2 days after surgery was recorded. RESULTS: Patient characteristics were similar in both groups at both the hospitals. The median postoperative pain score of VAS <3 was observed in both groups. Significant difference (p < 0.0001) was observed in the VAS scores between the two groups at all the time intervals. The mean length of adequate sensory block in group 1 was significantly higher than in group 2 [20.5 h: 4.2 h] (p < 0.001). The mean analgesic (morphine) consumption was lower in Group 1 as compared to Group 2 [4.6 mg/24 h: 18.8mg/24 h](p < 0.0001). Bone shaving procedures e.g. SAD, SAD + Rotator Cuff repair, SAD + Lateral clavicular excision required significantly higher analgesia in both groups compared to the soft tissue procedures. CONCLUSION: Single dose ISB provided longer and effective postoperative analgesia. The bone shaving procedures required more analgesia in IA Group as compared to ISB Group.
