ABSTRACT
Objective:To compare the training effect between the laparoscopic simulated uterine model (LSUM) with multi-angle suture and the traditional surgical model and to identify a laparoscopic model more suitable for gynecological resident training.Methods:Forty-eight residents who were trained in Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine from February 2021 to February 2023 were selected. They were trained in batches, with each batch randomly divided into two groups of the same size. The observation group was trained with the traditional surgical model and general surgical videos, while the experimental group was trained with a self-developed LSUM with multi-angle suture and corresponding surgical videos. Finally, the two groups were compared for the assessment results, and a questionnaire survey was conducted in the experimental group. The statistical software SPSS 20.0 was used for t-test or chi-square test of the results. Results:There were no significant differences between the two groups in age, gender distribution, education level, and clinical experience. In theoretical assessment results, no significant difference was shown between the experimental group and the observation group [(82.63±3.93) vs. (85.00±6.15), P>0.05]. In skill assessment results, there was no significant difference between the two groups in the anterior wall assessment [(83.08±4.47) vs. (82.79±3.58), P=0.804]. However, in the assessment of the lateral and posterior walls, the proficiency, accuracy, and degree of coordination between two hands of the experimental group were better than those of the observation group, with the total score being significantly different [(64.13±3.34) vs. (46.75±3.50), (62.25±4.41) vs. (45.00±2.89), P<0.001]. In the questionnaire survey, the experimental group had a high degree of satisfaction with the LSUM and thought that the highly simulated model was beneficial to their training. Conclusions:Compared with the traditional surgical model, the LSUM with multi-angle suture can effectively improve the operation level of residents, which provides a new idea for the laparoscopic simulation training of gynecological residents in the future.
ABSTRACT
Objective:To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS).Methods:This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration.Results:(1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant ( P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups ( P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion:The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.
ABSTRACT
Standardized training of residents is an important measure to cultivate medical talent.Hysteroscopy is an important teaching content in the standardized training of obstetrics and gynecology residents.A variety of teaching and training methods has been employed in department of obstetrics and gynecology in Sir Run Run Shaw Hospital affiliated to School of Medicine of Zhejiang University including theory teaching,teaching rounds,PBL,trainee training,one to one training,skill assessment to improve the quality of the standardized training and the practical ability of the residents.
ABSTRACT
Objective To explore the effects of information support on anxiety and sleeping quality of puerpera with postpartum hemorrhage. Methods A total of 120 puerpera with postpartum hemorrhage who were hospitalized and delivered in our hospital from August 2011 to August 2014 were selected. They were randomly assigned to a control group and an experimental group, with 60 in each. The control group was given regular postpartum care, and the experiment group was given information support on the basis of regular care. Sleep quality, anxiety degree and mental state of puerpera in the two groups were compared. Results SAS score in the experimental group was significantly lower than that in the control group, and the difference was statistically significant (P<0.05). The number of puerpera with normal health state and the number of puerpera with mild anxiety in the experimental group were both more than those in the control group, and the number of puerpera with moderate to severe anxiety was less than that in the control group. The differences above were all statistically significant (P<0.05). Total PSQI score in the experimental group was significantly lower than that in the control group, and the sleeping quality in the experimental group was better. All the differences above were statistically significant (P<0.05). Total SCL-90 score in the experimental group was significantly lower than that in the control group, and scores of somatization, terror, anxiety, depression and interpersonal relationship were lower than those in the control group. All the differences above were statistically significant (P<0.05). Scores of hostility, paranoid, psychoticism and OCD compared between the two groups were similar, and the differences were not statistically significant (P>0.05). Conclusion Information support for puerpera with postpartum hemorrhage is able to reduce anxiety degree, improve sleeping quality, and enhance mental state, which is beneficial for the recovery of puerpera.
ABSTRACT
<p><b>BACKGROUND</b>Reduced endometrial receptivity in hyperstimulated cycles may lead to a lower implantation rate and a lower clinical pregnancy rate, but it is unclear if it is also associated with an increase in pregnancy loss rate. The aim of this study was to compare the implantation, miscarriage, and pregnancy rates between fresh and frozen thawed transfer of one or two day-3 embryos, with a view to understanding whether or not reduced endometrial receptivity encountered in hyperstimulated cycles is associated with an increase in miscarriage rate.</p><p><b>METHODS</b>This study involved a consecutive series of 1 551 single day-3 embryo transfer cycles and consecutive 5 919 double day-3 embryo transfer cycles in the Assisted Reproductive Unit of the Sir Run Run Shaw Hospital, Hangzhou, China, between January 2010 and December 2012.</p><p><b>RESULTS</b>The implantation and clinical pregnancy rates (single embryo 30.7% and double embryos 33.4% and 51.4%) using fresh cycle were both significantly lower than that of frozen-thawed cycles (single embryo 35.8% and double embryos 38.1% and 57.8%). There was no difference in biochemical loss or clinical miscarriage rates between the two groups.</p><p><b>CONCLUSIONS</b>Impairment of endometrial receptivity associated with ovarian hyperstimulation leads to implantation failure at a very early stage, resulting in an increased number of non-pregnancy. It does not lead to increase in biochemical or clinical losses. The significantly reduced ongoing pregnancy rates in both fresh single and double embryo transfer are therefore due to failure to achieve a pregnancy, rather than pregnancy loss after conception.</p>

15 oocytes group than in the ≤15 oocytes group. All parients with the acute abdmen caused by ectopic and heterotopic pregnancy had tubal factor causing infertility. The misdiagnostic rate was significantly lower of reproductive-specialty doctors than non-reproductivespecialty doctors. Conclusion Excessive oocytes induced by ovarian hyperstimulation and tubal damage were main risk factors of acute abdomen. To reduce the misdiagnosis, non-reproductive-specialty doctors should know about IVF-ET and patients should be informed about the occurrence of these procedure related complications.
ABSTRACT
Objective To investigate the effects and outcomes of four procedures for hysterectomy. Method Retrospectively, we analyzed the clinical characteristics of 756 cases who respectively received hysterectomy by total abdominohysterectomy (TAH,260 cases), modified abdominohysterectomy (MAH, 180 cases), transvaginal hysterectomy (TVH, 106 cases), or laparoscopic assisted vaginal hysterectomy (LAVH)(210 cases) and compared their effects and outcomes. Results The average operation time of TAH(98 ?23)minutes, MAH(67?18)minutes, TVH (63?19)minutes and LAVH(99?35)minutes. The average operation time of LAVH and TAH groups was significantly longer than that of TVH and MAH groups (P
