In this prospective, randomized, blinded study, we assessed the analgesic efficacy of interscalene brachial plexus block (ISB), suprascapular nerve block (SSB), and intraarticular local anesthetic (IA) after arthroscopic acromioplasty. One-hundred-twenty patients were divided into 4 groups of 30. In Group SSB, the block was performed with 10 mL of 0.25% bupivacaine. In Group IA, 20 mL of 0.25% bupivacaine was administered intraarticularly at the end of surgery. In Group ISB, the block was performed with 20 mL of 0.25% bupivacaine. A control group was included for comparison. General anesthesia was administered to all patients. Patients were observed during the first 24 h. Pain scores, supplemental analgesia, satisfaction scores, and side effects were recorded at 4 and 24 h. No significant difference was observed between the IA and control groups. When compared with these groups, Groups SSB and ISB had significantly lower pain scores. At 4-h follow-up, better pain relief on movement was noted in Group ISB than in Group SSB. When compared with controls, a significant reduction in morphine consumption and a better satisfaction score were noted only in Group ISB. We conclude that ISB is the most efficient analgesic technique after arthroscopic acromioplasty. SSN block would be a clinically appropriate alternative.

Background:Studies evaluating the hemostatic effects of fibrinogen administration in cardiac surgery are not conclusive.Aims:We investigated whether the use of a low-dose human fibrinogen in case of clinical bleeding after protamine administration and concomitant low FIBTEM values is effective in reducing postoperative bleeding. Secondary end-point was to investigate the consumption of allogeneic blood products.Setting and Design:This was a retrospective matched study conducted at university hospital.Materials and Methods:Among 2257 patients undergoing surgery with cardiopulmonary (CPB) bypass, 73 patients received a median dose of 1 g human fibrinogen (ROTEM-Fibri group). This group was matched with 73 patients who had not received human fibrinogen (control group) among 390 patients having undergone surgery at the moment FIBTEM analysis was unavailable.Statistical Analysis:Matching was performed for the type and the presence of redo surgery. McNemar and Wilcoxon paired tests were used to respectively compare the categorical and quantitative variables.Results:The CPB bypass time was significantly higher in the ROTEM-Fibri group (P = 0.006). This group showed significantly higher bleeding in the first 12 and 24 h postoperatively (P < 0.001) and required significantly more transfusion of blood products (P < 0.001) and surgical revision (P = 0.007) when compared with the control group. There was no significant difference in the number of thromboembolic complications.Conclusions:These results show that the administration of 1 g of fibrinogen based on low-FIBTEM values and clinical bleeding after protamine administration does not stop bleeding and the need for transfusion of allogeneic blood products.
