简要总结
The combination of a modified lateral sagittal infraclavicular block and a suprascapular nerve block has not been studied in a cohort of total arthroplasty patients. Such diaphragm-sparing nerve blocks for shoulder arthroplasty may provide a very good anesthetic alternative in lung diseased patients who are in need for total arthroplasty of the shoulder.
详细描述
The investigators hypothesized that a combination of suprascapular nerve block and lateral sagittal infraclavicular block of the posterior and lateral cords would provide good postoperative analgesia for patients undergoing shoulder arthroplasty.
The primary aims of this study were to document numeric rating scale (NRS, 0-10) and use of morphine equivalents during the first 24 hours after surgery. Secondary aims were to determine the incidence of diaphragm paresis 30 minutes after the block and to quantify postoperative hand grip force at 1 hr.

结局指标
主要结局
The incidence ipsilateral hemidiaphragmatic paralysis after 30 minutes
时间窗: 30 minutes after the blocks
Hemidiaphragmatic paralysis was defined as the absence of diaphragmatic motion during normal respiration, coupled with absent or (paradoxical) cranial diaphragmatic movement when the patient forcefully sniffed.
NRS
时间窗: Postoperatively at 1 hour
Pain on a 0-10 scale where 0=no pain and 10=unbearable pain
