BACKGROUND AND AIMS: Perineural catheters inserted through the costoclavicular (CC) technique of infraclavicular brachial plexus are helpful for postoperative analgesia. This trial compared postoperative local anaesthetic (LA) consumption in an ultrasound (US)-guided perineural catheter inserted by the CC technique with the conventional lateral sagittal (LS) technique.
METHODS: Eighty American Society of Anesthesiologists (ASA) I/II patients scheduled for upper limb orthopaedic surgery were randomly assigned to receive a perineural catheter by either the CC technique (Group CC) or LS technique (Group LS). Postoperatively, all patients received patient-controlled regional analgesia (PCRA): bolus-only regime with 0.125% bupivacaine 6 ml and a lock-out interval of 20 minutes. The primary outcome was the 24 h LA consumption. The secondary outcomes were time of activation of PCRA, pain scores, patient satisfaction scores, and block-related complications. Categorical variables are presented as frequency, while continuous variables are expressed as mean [standard deviation (SD)] or median [interquartile range (IQR)]. An independent t-test or Mann-Whitney U-test was used to compare these continuous variables. A P value less than 0.05 was considered to be statistically significant.
RESULTS: Patients in Group CC required less LA 24 h postoperatively (P < 0.001) and more time to activate PCRA (P = 0.003). The mean 24 h LA requirement was 83.35 (SD: 31.92) in Group CC as compared to 121.40 (SD: 48.51) ml in Group LS. They also reported better satisfaction scores (P = 0.001). Pain scores were comparable at all time points. Postoperatively, one patient in Group CC complained of paraesthesia, which subsided on removal of the catheter.
CONCLUSION: Patients receiving post-operative analgesia by the CC catheter require lesser 24 h LA and report better satisfaction than those receiving analgesia through the LS technique.
