Incidence of post-dural lumbar puncture headache (PDLPH) in comparison between emergency and elective lower segment cesarean section (LSCS) with 26G Quincke-Babcock cutting-beveled spinal needle

Abstract

Background: C-section is usually performed under spinal anesthesia also known as a subarachnoid block (SAB) over general anesthesia. Because of the lesser amount of dose used, there is a lower risk of local anesthetic toxicity and minimal transfer of drugs to the fetus. Obstetric patients have a higher risk of having post-dural puncture headache (PDPH). PDPH occurs due to leakage of the cerebrospinal fluid (CSF) through the hole created by a spinal needle. There are many elements affecting the frequency of PDPH, these elements can also consist of age, female sex, needle size, and types, pregnancy, preceding records of PDPH, median-paramedian distinction in approach, a puncture level. PDPH is commonly in the form of a frontal, occipital, or retro-orbital headache that starts in 12-72 h after the dural puncture and will increase when standing and decrease when lying down or resting. We aimed to learn about headache frequency between elective and emergency lower segment cesarean section using 26-G Quincke spinal needle in full-term pregnant patients.

Objectives: To study the incidence of PDPH using the 26G Quincke spinal needle. To analyze the causal factors/determinants such as adequate preloading of fluids, size of spinal needle, number of pricks, and technique of lumbar puncture effects on the incidence of PDPH.

Methodology: This study is a prospective questionnaire-based comparative observational study using the convenience sampling method. The patients were interviewed with a structured questionnaire at the Symbiosis University Hospital and Research Centre, Lavale, Pune. The patients observed for the study were between 20 and 40 of age group, posted for emergency or elective lower segment cesarean section, with body mass index (BMI) less than 14.5 to 24.9 and with ASA I and II grades. Patients with any comorbidities, recurrent headaches, obesity, and spine deformity were excluded. According to the review of the literature and with the help of a formula, the sample size was calculated as 20; 10 patients for elective LSCS, and 10 patients for emergency LSCS.

Results: Out of 20 patients, 10 patients were posted for elective LSCS, and the rest 10 patients were for emergency LSCS under spinal anesthesia. The incidence of PDPH was found only in 2 out of 10 emergency LSCS patients, and no patients from elective LSCS cases showed up with the incidence of PDPH.
