ObjectiveTo compare the clinical efficacy of methotrexate perfusion combined with interventional treatment and the traditional treatment with methotrexate and mifepristone for cesarean scar pregnancy. MethodA total of 589 patients diagnosed with cesarean scar pregnancy after surgery between January 2012 and March 2015 in our hospital were selected to be our study subjects. The patients were informed of the two kinds of treatment, and based on their own will, they were arranged into corresponding groups. Group A had 234 patients who were willing to undergo the conventional therapy:intramuscular injection of methotrexate (20 mg, once per day for 5 days); oral mifepristone (50 mg once per day for 3 to 5 days); and the continuation of drugs was determined by local pregnancy tissue blood flow on B ultrasound and liver function of the patients. Group B had 255 patients who selected uterine artery perfusion and arterial embolism. There was no significant difference in terms of age, serum human chorionic gonadotrophin (HCG) and uterine incision gestation sac size between the two groups of patients (P>0.05). Then we compared the treatment effect between the two groups. ResultsThe differences in the amount of bleeding, the time of blood HCG dropped to normal, and hospitalization duration between the two groups were significant (P<0.05), while in the rate of hysterectomy, drug-induced liver injury were not (P<0.05). ConclusionsMethotrexate perfusion combined with interventional treatment is better than the traditional treatment with methotrexate and mifepristone for cesarean scar pregnancy in terms of clinical efficacy and safety.
ObjectiveTo systematically review the prevalence and risk factors of the chronic post-cesarean section pain (CPCSP). MethodsPubMed, EMbase, The Cochrane Library, CINAHL, PsycInfo, CBM, WanFang Data, VIP, and CNKI databases were electronically searched to collect studies on the prevalence and risk factors of CPCSP from inception to August 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 15.1 software. ResultsA total of 43 studies involving 12 435 participants were included. The results of meta-analysis showed that the prevalence of CPCSP for 2 to 5 months, 6 to 11 months, and at least 12 months were 19% (95%CI 15% to 23%), 13% (95%CI 9% to 17%), and 8% (95%CI 6% to 10%), respectively. The risk factors included preoperative pain present elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety, postpartum depression, etc. ConclusionsThe current evidence shows that the overall prevalence of CPCSP is high. Preoperative pain presents elsewhere, postoperative severe acute pain, low abdominal transverse incision, non-intrathecal administration of morphine, preoperative anxiety and postpartum depression may increase the risk of CPCSP.
ObjectiveTo explore the therapeutic effects of different surgical strategies on women with mechanical valve dysfunction during pregnancy.MethodsA total of 11 patients with mechanical valve dysfunction during pregnancy who underwent surgeries in our hospital from 2007 to 2017 were retrospectively included. The average age was 27.5±3.7 years. The prognosis of patients was analyzed according to the gestational weeks, cardiac function and the severity of mechanical valve dysfunction.ResultsNo death occurred. Three of them suffered subtotal hysterectomy during the surgery because of uncontrolled bleeding, and the others recovered without complications. Among the 5 patients with pregnancies <28 weeks, 1 patient was found intrauterine death before hospital admission, 2 suffered fetal loss 5 days after the cardiac surgery, and the other 2 patients continued their gestations until deliveries. Among the other 6 patients with pregnancies >28 weeks, 1 fetus died because of intracranial hemorrhage, and the other 5 survived without embryopathy or foetopathy.ConclusionGestation week, cardiac function and severity of mechanical valve dysfunction may be taken into account when making a treatment regimen for women with dysfunctional valve prostheses during pregnancy.
目的 系统评价瑞芬太尼用于全身麻醉下剖宫产时对新生儿的影响。 方法 检索Cochrane Library、PubMed、OVID、EMbase、CNKI、万方等中外数据库，收集1990年－2012年关于瑞芬太尼用于全身麻醉下剖宫产的临床随机对照研究。按Cochrane系统评价方法评估文献质量，用Revman 5.1软件对提取的数据进行Meta分析。 结果 共纳入10项研究，包括342例产妇。与空白对照组相比，瑞芬太尼降低新生儿1 min Apgar评分[WMD=?0.46，95%CI（?0.65，?0.27），P＜0.000 01]，提高出生时脐动脉pH值[WMD=0.01，95%CI（0.00，0.02），P=0.004]，增加出生时窒息发生率[RR=1.76，95%CI（1.06，2.95），P=0.03]；当诱导剂量为1.0～1.5 μg/kg时，对5 min Apgar评分无影响[WMD=?0.14，95%CI（?0.32，0.04），P=0.13]。 结论 瑞芬太尼用于全身麻醉剖宫产可减轻新生儿酸中毒，但是会对新生儿产生一过性的呼吸抑制。

Objective To assess the efficacy and safety of chewing gum in promoting bowel recovery after cesarean section. Methods Such databases as The Cochrane Library, MEDLINE, EMbase and CBM were searched from their establishment to 2010 to include the randomized controlled trials (RCTs) of comparing chewing gum with other procedures for promoting postoperative bowel function after cesarean section. The risks of bias in the included studies were evaluated at randomization, allocation concealment, blinding, completeness of outcomes, and selective reporting. Meta-analyses were performed by RevMan 5.0.22 software. Results Three RCTs involving 745 participants were included. The results of meta-analyses showed chewing gum after cesarean section significantly shortened the time before getting the first postoperative flatus (MD= –6.54, 95%CI –7.82 to –5.27, Plt;0.000 01), reduced the risks of postoperative ileus (RR=0.54, 95%CI 0.34 to 0.87, P=0.01) and possibly shortened the length of hospital stay (MD= –0.21, 95%CI –0.39 to –0.03, P=0.02) compared with blank control. Currently, no adequate data supported the safety of chewing gum after cesarean section. Conclusion Chewing gum after cesarean section can promote the postoperative bowel recovery, and reduce the odds of postoperative ileus. However, more high quality RCTs are required for lack of included studies and poor quality of methodology.

Objective To discuss the effect of continuous phenylephrine infusion and single-dose phenylephrine injection on puerpera undergoing spinal and epidural combined anesthesia and the infant outcomes. Methods A total of 50 patients scheduled for selective cesarean section under combined spinal and epidural anesthesia were selected as the study subjects between July 2015 and June 2016. They were randomly allocated into two groups with 25 in each. Group CII underwent continuous phenylephrine infusion [0.5 μg/(kg·min)] immediately after anesthesia to adjust the blood pressure, while group CON accepted single-dose phenylephrine injection (50 μg) after anesthesia when systolic pressure was lower than 90 mm Hg (1 mm Hg=0.133 kPa) or when the decrease of mean arterial pressure (MAP) was higher than 20% of the base value. The infusion of phenylephrine was stopped after the fetus was taken out. MAP, cardiac output, cardiac index (CI) at the time when the patient went into the delivery room (T1), before anesthesia (T2), 1 minute after anesthesia (T3), 3 minutes after anesthesia (T4), 10 minutes after anesthesia (T5), and delivery (T6) were recorded. Blood gas analysis of fetal umbilical arterial blood was carried out and neonatal Apgar score was recorded. Results Hemodynamics was more stable in group CII compared with group CON. Heart rate at T4 and T5, and cardiac output at T5 and T6 in group CON were significantly lower than those in group CII (P<0.05). The neonatal umbilical arterial blood pH value, base excess and HCO3－ were all significantly lower, while partial pressure of carbon dioxide was significantly higher in group CON than group CII (P<0.05). Conclusion Compared with single-dose phenylephrine injection, continuous phenylephrine infusion has more stable hemodynamics, and exert less effect on maternal and infant outcomes for patients undergoing cesarean section under combined spinal and epidural anesthesia.
