目的：探讨腹腔镜术后肩部疼痛与CO2气腹压力、时间的关系。方法经患者知情同意及医院伦理委员会批准，将60例接受腹腔镜手术的患者分为2组，A组（30例）CO2气腹压力设为9 mmHg，B组（30例）CO2气腹压力设为13 mm-Hg。观察比较2组24 h内肩痛发生率。另选50例分为手术时间在1 h以内的C组及2 h以上的D组，观察比较2组24 h内肩痛发生率。结果 A组24 h内4例患者发生肩痛，占13．3％；B组12例，占40．0％。2组差异有统计学意义（χ2＝5．455， P＜0．05）。C组3例，占14．3％；D组4例，占13．8％。2组差异无统计学意义（χ2＝0．00254，P＞0．05）。结论腹腔镜手术后肩部疼痛与CO2气腹产生的张力有关，但与气腹时间长短无明显相关性。%Objective To explore the relationship between shoulder pain and carbon dioxide ( CO2 ) pneumoperitoneal pres-sure and time following laparoscopic surgery .Methods Sixty patients who underwent laparoscopic surgery were randomly divided into group A and group B .The pneumoperitoneal pressure for group A was set at 9 mmHg and that for group B was set at 13 mmHg.Then, incidence rates of shoulder pain in 24 hours were observed and compared between the 2 groups.Another 50 patients were divided into group C (whose surgery time was 1 h) and group D (whose surgery time was 2 h).Incidence rates of shoulder pain for the latter 2 group in 24 hours were also observed and compared .Results There were 4 cases in group A, accounting for 13.3%, and there were 12 cases in group B, accounting for 40.0%(χ2 =5.455, P<0.05).Significant differences could be seen , when comparisons were made between the 2 groups.There were 3 cases in group C, accounting for 14.3%, and there were 4 cases in group D, accounting for 13.8%(χ2 =0.002 54,P >0.05).There were no significant differences, when comparisons were made between the 2 groups. Conclusion Shoulder pain after laparoscopic surgery was associated with the tension induced by CO 2 pneumoperitoneum , however, there was no obvious correlation between duration of pneumoperitoneum and shoulder pain .
