目的 探讨垂体后叶素用于宫腔镜子宫肌瘤电切术对出血量及液体吸收的影响.方法 2006年1月-2007年12月,48例子宫粘膜下肌瘤拟行宫腔镜下子宫肌瘤电切术者随机分为观察组24例及对照组24例.观察组在宫颈口扩张后于宫颈旁注射稀释垂体后叶素6U,对照组除术中未用垂体后叶素,其他术前准备及手术步骤同观察组.结果 观察组手术时间(32.2±5.0)min,明显短于对照组(38.9±6.8)min;观察组液体用量(2978.1±860.5)ml明显少于对照组(3451.2±826.8)ml;观察组液体吸收量(245.3±80.1)ml少于对照组(321.4±85.3)ml;观察组液体吸收率(7.5±1.1)%,少于对照组(9.2±1.1)%;观察组术中出血量(20±5)ml少于对照组(35±5)ml.结论 术中应用稀释垂体后叶素可减少术中出血,提高视野清晰度,缩短手术时间,减少膨宫液用量及吸收率,有效预防经尿道前列腺电切(transurethal resection ofthe prostate,TURP)综合征等并发症的发生.%Objective To investigate the effect of Pituitrin on the bleeding and fluid absortion of myoma electrotomy in hysteroscope Method 48 patients diagnosed with submucous myoma between January 2006 to December 2007 were divided into two groups at random, one was the observing group (24 cases, the other was the control group 24 cases, which were arranged to be treated with the myoma electrotomy in hysteroscope.After the dilation of the cervix, the observing group were injected 6U diluted Pituitrin beside the cervix, while the control group did not use the Pituitrin. Result The operation time of the observing group (32. 2 ± 5. 0) min was obviously less than the control group (38. 9 ± 6. 8)min. The fluid consumption of the observing group (2978. 1 ± 860. 5) ml was obviously less than the control group (3451. 2 ± 826. 8)ml.The absorbed dose was of the observing group (245. 3 ± 80. 1) ml is obviously less than the control group (321.4 ± 85. 3) ml. The absorptivity of the observing group (7. 5 ± 1. 1)% was also less than that of the control group (9. 2 ± 1. 1)%. The bleeding of the observing group (20 ± 5) ml was less than that of the control group (35 ± 5) ml. Conclusion Using diluted Pituitrin in the operation can diminish the bleeding of the operation, improve the legibility of the vision, shorten the operation time, diminish the dose as well as the absorptivity of the expanding liquid, which can prevent the TURP (transurethal resection of the prostate) effectively.
