ABSTRACT
Objective To investigate the postoperative analgesia efficacy of ultrasound-guided rectus abdominis sheath block (RSB) in patients with abdomen panhysterectomy.Methods Forty patients with abdomen panhysterectomy under general anesthesia were divided into RSB group and control group by random digits table method with 20 cases each.All the patients were given patient controlled intravenous analgesia.The visual analogue scale (VAS) score and Ramsay sedative score at 2,6,12 and 24 h after operation,sulfentanyl dosage and total number of analgesic pump press of 24 h,number of nausea and vomiting,analgesic satisfaction score were recorded.Results The VAS scores in RSB group at 2,6,12,24 h after operation were lower than those in control group,but there were no statistical differences (P＞ 0.05).The Ramsay sedative score of all patients was ＜ 4 scores.Sulfentanyl dosage of 24 h in RSB group was (73.1 ± 8.6) μ g,in control group was (91.7 ± 12.3) μ g,there was statistical difference (P ＜ 0.01).The number of analgesic pump press of 24 in RSB group was (6.5 ± 2.1) times,in control group was (12.3 ± 4.6)times,there was statistical difference (P ＜ 0.01).Analgesic satisfaction score in RSB group was (7.3 ± 0.7)scores,in control group was (6.8 ± 1.1) scores,there was statistical difference (P＜ 0.05).Four cases in RSB happened nausea and vomiting,3 cases in control group,there was no statistical difference (P ＞ 0.05).All patients did not happen the complication related with RSB operation.Conclusion RSB as the postoperative analgesia in patients with abdomen panhysterectomy can reduce the dosage of opioid drug,and increases the analgesic satisfaction.
