Ruptured uterus: Frequency, risk factors and feto-maternal outcome: Current scenario in a low-resource setup.

INTRODUCTION: Pakistan is among the countries with the highest maternal death rates. Obstetric hemorrhage accounts for 41% of these deaths. Uterine rupture is a grave obstetric emergency with high maternal and neonatal morbidity and mortality. It is important to identify its frequency and associated risk factors to formulate programs for its prevention and management. This study aimed to assess the frequency, associated risk factors, fetomaternal outcomes, and management of women with the ruptured uterus at our hospital. MATERIAL AND METHODS: It was a retrospective study of 206 women to review data collected from cases of uterine rupture managed at the WCTH Bannu, Pakistan from October 2016 to October 2018. A structured proforma was designed and used to extract data from operating theatre registers and the hospital medical records. In our hospital, there is a strong system of maintaining all information of the patients related to demographics, obstetric information, operative notes, and postoperative course during their hospital stay in the patient's charts. Detailed information on operative procedures is further maintained in the operation theater register and all these registers are checked in the weekly statistical meetings to ensure proper documentation. Data was entered and analyzed in SPSS package version 21 (IBM Corp.; Armonk, NY, USA). Frequency and percentages were calculated for the categorical variables. For inferential statistics, chi-square or Fischer exact tests were used. A p-value of < 0.05 was considered statistically significant. RESULTS: The overall incidence of the ruptured uterus was 1.71%. The important etiological factors were grand multiparity 62 (35.2%), obstructed/neglected labour 58 (32.9%), injudicious use of Oxytocin 56 (31.8%) and prostaglandins 26 (14.7%), previous cesarean section 35 (19.8%) and previous pelvic surgery (0.5%). Hysterectomy was done in 80.6% of cases, 34 (19.2%) patients underwent uterine repair and 4.5% had bladder repair. The mortality rate was 21%, mainly due to irreversible shock or disseminated intravascular coagulation. Perinatal mortality was 91.4%. Duration of surgery more than two hours and presentation to the hospital at night time was significantly associated with poor maternal outcome (p = 0.00). CONCLUSION: Uterine rupture is a preventable obstetric emergency associated with high fetomaternal morbidity and mortality. The main causes were grand multigravidity, obstructed labour, previous C-sections and injudicious use of oxytocin and prostaglandins. Women with prolonged surgery and admission at night time had a poor maternal outcome.

Evaluating Predictive Value of Preoperative Clinical and Imaging Findings on the Short-Term Outcome of Surgery in Patients Undergoing Lower Lumbar Discectomy.

OBJECTIVE: The most common indications for spinal surgery are low back pain and associated disabilities caused by disc herniation. Given the high prevalence of low back pain, the critical nature of pain assessment in these patients, and knowledge about the influencing and predisposing factors, we sought to evaluate the clinical and radiologic findings associated with pain relief and postoperative recovery in patients who underwent bilateral lumbar discectomy. METHODS: From March 2016 to October 2020, a prospective cohort study was conducted. This study included adult patients with symptomatic disc herniation in the L4-L5 and L5-S1 segments who were candidates for bilateral discectomy. Before and after surgery, patients were evaluated for lumbar and radicular pain and the Oswestry Disability Index (ODI) score and at the four, 12, and 24-week follow-up. Meanwhile, a variety of demographic, clinical, and radiologic factors was collected and statistically analyzed. RESULTS: This study enrolled 30 patients. The average age of the patients was 41.2 years, with 22 males and eight females. Twelve of these patients had disc involvement in the L4-L5 region, while 18 had disc involvement in the L5-S1 region. Statistical analysis revealed that radicular pain and disability associated with low back pain significantly decreased following surgery (P=0.001). However, there was no significant reduction in back pain (P>0.05). Patients with a higher body mass index (BMI) and neurological claudication had a lower reduction in radicular pain (P<0.05). Moreover, a higher BMI and the presence of instability pain are associated with an increased likelihood of postoperative lumbar pain relief (P<0.01). Among the radiological variables, increased disc height was associated with a more rapid recovery from low back disability (P=0.003). Furthermore, a larger diameter of paraspinal muscles at the level of the herniated disc was associated with a more rapid improvement of lower back pain (P=0.021). CONCLUSION: The use of discectomy in patients with lumbar disc herniation significantly alleviates postoperative and follow-up radicular pain. Age, BMI, neurological claudication, instability pain, and paraspinal muscle diameter played a role in postoperative pain relief. Increased disc height was associated with a more rapid decline in the ODI score. Future studies with larger sample sizes are recommended.
