Evaluatıng the Role of Overactıve Bladder Dıagnosıs ın Predıctıng the Rısk of Postspınal Hypotensıon Durıng Electıve Cesarean Sectıon Operatıons: Randomızed Trıple-Blınded Study.

Background: It is important to predict hypotension following spinal anesthesia (SA) during cesarean section (C/S), in terms of preventing the adverse affects.

Aim: The aim of this study is to evaluate diagnosing overactive bladder via the overactive bladder (OAB)-V8 questionnaire that could be a prediction method for postspinal hypotension during elective cesarean section under combined spinal-epidural anesthesia.

Materials and methods: This study was carried out on 143 primipara women in the third trimester planned for elective cesarean section under combined spinal-epidural anesthesia. Each primipara parturient in her third trimester was seen by a urology specialist for diagnosis before surgery, where she was directed to the OAB-V8 questionnaire in Turkish. Patients diagnosed with overactive bladder were recorded under Group I, and the others under Group II.

Results: 39,9% of patients had hypotension. Hypotension occurrence was statistically higher in Group I than in Group II (47% vs 30%). According to the diagnostic test results for using overactive bladder diagnosis in the prediction of hypotension, the sensitivity was 68%, the specificity was 49%, positive predictive values were 47%, and negative predictive values were 70%.

Conclusion: The risk of postspinal hypotension in parturients with overactive bladder is higher. Higher caution must be taken for hypotension after SA intervention in patients with over active bladder.
