ObjectiveTo study the effects of ultrasound guided inter-scalene brachial plexus block and patient-controlled infraclavicular brachial plexus block for postoperative pain and surgical efficacy in patients with terrible tyriad of the elbow.MethodsFrom March 2015 to August 2016, 60 patients with terrible tyriad of the elbows were treated in Ningbo No.6 Hospital with ASA I to II internal fixation. There were 32 males and 28 females, ranging in age from 16 to 70 years old, with a mean age of (55.6±18.2) years old. All the patients were divided into two groups(30 cases in each group): controlled intermuscular groove brachial plexus block (group C), infraclavicular brachial plexus block(group I). All catheters were placed using ultra-sound visualization and injected 0.33% ropivacaine 30 ml preoperatively. After regaining consciousness, all patients connected the electronic pump. The solution contained 0.2% ropiva-caine and the pump was setup to deliver a 5 ml bolus dose, with a 15 min lock out interval and background infusion at 5 ml/h. Both analgesia lasted until 5 d after operation. The patients underwent rehabilitation exercise everyday for 5 consecutive days starting from 24 h after operation.VAS score was recorded at 24 h, 48 h, 72 h and 4 d, 5 d after operation during rest and rehabilitation exercise time. The elbow articular range of motion and Mayo elbow performance score (MEPS) were recorded at 6 d after operation. Catheter-related adversereactions (such as oozing from the insertion site, obstruction, prolapse) were recorded.ResultsThe success rate of blockade was 100% during insertion in both groups. Compared with group C, the VAS score at 3 d during rest time and 3, 4, 5 d after operation during rehabili-tation exercise were decreased(2.5±0.5 vs. 3.8±1.1, 3.0±0.4 vs. 5.0±0.9, 2.5±0.4 vs. 4.5±1.2, 2.1±0.3 vs. 4.1±1.0, P<0.05). The elbow articular range of motion and MEPS were increased(-2.19±18.01)° vs.(-8.19±12.16)°, (45.15±11.20)° vs. (22.15±7.02)°, (19.06±6.75)° vs. (9.10±2.48)°, (17.08±5.18)° vs. (10.12±3.15)°, (80.80±9.50) points vs. (64.90±11.21) points. The incidence of insertion site, obstruction, prolapse was 15, 5 and 10 cases respectively in group C, but without any catheter-related adverse reactions happened in group I (P<0.05).ConclusionsPatient-controlled infraclavieular brachial plexus block can be effectively used for postoperative pain after fixation for terrible tyriad of the elbows, and it can increase surgical outcome.
