Abstract
Introduction: Interscalene brachial plexus block with continues catheter insertion system and a disposable infusion pump is a commonly employed technique for upper limb surgeries. Postoperatively these patients may be managed by various methods like rescue opioids depending upon VAS score, patient controlled analgesia or a combination of these two. Interscalene brachial plexus block with a continuous catheter insertion system and a disposable infusion pump through which local anesthetic drug is infused perineurally is an effective alternative for providing postoperative analgesia in patients who have undergone various upper limb surgeries. We conducted this comparative study to find out the efficacy of Interscalene brachial plexus block with a continuous catheter insertion system and a disposable infusion pump in providing postoperative analgesia in patients who have undergone open reduction and internal fixation for fracture head of humerus.
Aims and Objectives: To study the efficacy of Interscalene brachial plexus block with a continuous catheter insertion system and a disposable infusion pump in providing postoperative analgesia in patients who have undergone open reduction and internal fixation for fracture head of humerus.
Materials and Methods: This was a comparative study in which total 30 patients who have undergone open reduction and internal fixation for fracture head of humerus were included depending upon inclusion and exclusion criteria. All the patients were operated under interscalene block using 30 ml of 0.5% Ropivacaine. Patients were divided into 2 groups. Group R received 0.2% ropivacaine infusion while Group S received Normal saline infusion for 24 hours postoperatively through continuous catheter insertion system and a disposable infusion pump. Demographic details, duration of surgery, postoperative VAS score and requirement of rescue analgesics were compared in both the groups.
Results: Mean age and mean duration of surgery were found to be comparable in both the groups and there was no statistically significant difference between these 2 groups. Hemodynamic parameters were also found to be comparable for initial 24 hours of postoperative period. Patients in group R (Ropivacaine Group) had significantly less requirement of rescue analgesic doses in postoperative period. Moreover mean VAS scores were found to be significantly low in Group R.
Conclusion: Interscalene brachial plexus block with continues catheter insertion system and a disposable Infusion Pump was found to be an effective method for providing postoperative analgesia to patients undergoing upper limb surgeries.
Keywords: Interscalene brachial plexus block, continues catheter insertion system, Ropivacaine.
