乳腺癌根治术采用高位硬膜外阻滞,术中常引起通气量不同程度下降,这早已为麻醉医生所熟知,因此对术后病人施行镇痛常有所顾虑。为了解术后镇痛是否会影响乳腺癌根治术后病人的呼吸功能,本研究观察比较了乳腺癌根治术后自控镇痛和非镇痛病人的呼吸功能变化及术后镇痛的可行性。1 The use of high epidural anesthesia in radical mastectomy for breast cancer, which often causes a decrease in ventilation during surgery, has long been known to anesthesiologists, and is therefore often a concern for postoperative analgesia. To understand whether postoperative analgesia affects the respiratory function of patients undergoing radical mastectomy, this study observed the feasibility of postoperative analgesia and postoperative analgesia in patients with self-controlled analgesia and non-analgesic therapy after radical mastectomy. 1
