【摘要】 目的 探讨减少输卵管间质部妊娠腹腔镜术中失血的方法。 方法 选择2007年1月-2010年6月49例诊断为输卵管间质部妊娠的患者随机分成观察组（24例）和对照组（25例）。观察组在腹腔镜切开异位妊娠病灶前于宫角注射垂体后叶素6 U，待子宫收缩后手术；对照组直接切开异位妊娠病灶进行手术。比较两组手术时间、术中出血量、血压、术后肛门排气时间、体温等方面的差异以及随访患者月经恢复时间。 结果 观察组和对照组手术时间分别为（34.29±7.96）、（53.68±10.48） min，术中出血量为（48.04±9.49）、（85.52±15.24） mL，差异有统计学意义（Plt;0.05）；两组在术后肛门排气时间、术后体温、术前血压、妊娠病灶切开后5 min的血压以及观察组使用垂体后叶素前后的血压差异均无统计学意义（Pgt;0.05）。两组患者在术后30～41 d月经复潮。 结论 输卵管间质部妊娠腹腔镜术中使用垂体后叶素能明显缩短手术时间和减少术中出血量，不增加持续性宫外孕的发生。【Abstract】 Objective To explore the method of reducing bleeding in laparoscopy for interstitial pregnancy. Methods Forty-nine patients diagnosed to have interstitial pregnancy between January 2007 and June 2010 were randomly divided into observation group (24 cases) and control group (25 cases). Patients in the observation group were given an injection of 6 U pituitrin in the horn of uterus before the incision of lesions in laparoscopy, and operation was performed after uterine contraction; while the lesions of patients in the control group were directly incised. The differences between the two groups in operation time, blood loss during the operation, blood pressure, exhaust time and temperature were studied and the recovery time of menstrual period was followed up. Results The operation time of the observation group and the control group was (34.29±7.96) minutes and (53.68±10.48) minutes; the blood loss was (48.04±9.49) mL and (85.52±15.24) mL, respectively. The difference in the operation time and blood loss between the two groups was significant (Plt;0.05). The difference in other indexes between the two groups such as the exhaust time, postoperative body temperature, the blood pressure before operation and within five minutes after the incision of the lesion was not statistical (Pgt;0.05). The recovery time of menstrual period in the two groups was 30 to 41 days. Conclusion Using pituitrin in laparoscopy for interstitial pregnancy can significantly shorten operation time and reduce blood loss, and will not increase the incidence rate of persistent ectopic pregnancy.
Objective To compare the outcome of uterine exteriorisation repair with in situ in caesarean section. Methods A randomized controlled trial with 220 cases were recruited. Woman with term singleton pregnancy underwent caesarean section and without severe complication were randomly allocated to the two groups (112 cases in exteriorisation group and 108 cases in situ group). Women in treatment group received exteriorisation when the uterus was sutured, While others had the uterus repaired in situ as control. Main outcome measures included perioperative haemodynamic parameters, loss of blood, changes in haemoglobin concentration, duration of operation, postoperative pain score and febrile days, gastrointestinal discomforts and function recovery as well as postoperative maternal morbidity.Data were analyzed by SPSS 11.0. Results Haemoglobin concentration dropped in both groups after caesarean section, and the drops in control group was significantly higher than that of treatment group (t=-2.902, P=0.004). In both groups, pulse before operation was markedly higher than when suturing the uterus and postoperation (Plt;0.05), but no difference was observed between the two groups. Systolic blood pressure of treatment group was lower than that of control group before operation, when suturing the uterus and after operation (F=5.246, P=0.022), but there was no difference among these 3 time points within the group. Onset of flatus was earlier in control group than in treatment group (t=5.567, P=0.000). No difference was identified between the two groups when receiving the different suturing methods. No severe maternal morbidity was observed.Conclusions Uterine exteriorisation and in situ repair have similar effects on intra- and postoperative outcomes. In routine process.
Objective To investigates the awareness of medical staff on prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) . Methods Between April and July 2014, health workers from towns and cities of Liangshan Prefecture participated in the class of prevention of HIV PMTCT for key areas in Sichuan province. Those participants, together with some other health workers from the same area whose daily work was related to prevention of PMTCT, were selected as the study subjects. PMTCT prevention knowledge survey questionnaire was given out for the investigation, and chi-square test was used for statistical analysis. Results We retrieved altogether 447 (out of 450) valid questionnaires. Of all the respondents, 94.18% were aware of proper time for HIV antibody testing and routes of transmission in the perinatal period, 95.30% knew the strategy of applying as early as possible antiviral drugs during pregnancy, and 86.58% learned to know when to give the first dose to the newborns and avoidance of breast-feeding. However, the awareness of relevant applied knowledge was relatively low. The total awareness rate of medical workers from women and children’s hospitals were significantly better than that of medical workers from general hospitals (P<0.05), and differences of the awareness depended on different specialties, professional titles and working age (P<0.05). Conclusions The majority of medical personnel in the surveyed area have grasped basic knowledge of PMTCT of HIV, but the ability of applying relevant knowledge precisely, promptly and standardly in daily practices needs to be improved. We recommend that, in addition to strengthening routine training on knowledge of PMTCT of HIV, the mastering and practice of key technical intervention strategies should be followed up and evaluated, especially for those from general hospitals. And it is also important to give training and after-training assessment based on different specialties.
