BackgroundThis double-blind, randomized trial compared dural puncture epidural analgesia (DPEA) for labor using 25-gauge and 27-gauge pencil point spinal needles. We hypothesized that both needle sizes would result in similar onset time (equivalence margin=2.5 min) and therefore designed the study as an equivalence trial.MethodsOne hundred and forty patients undergoing labor were randomized to DPEA with 25-gauge (n=70) or 27-gauge (n=70) pencil point spinal needles. After the placement of the epidural catheter, a bolus of 20 mL of bupivacaine 0.125% and fentanyl 2 µg/mL was administered to all subjects. Thereafter, patients received boluses of 12 mL of bupivacaine 0.125% every 2 hours as needed.A blinded investigator recorded the onset time (defined as the temporal interval required to achieve a pain score ≤1 on a 0–10 scale), S2 block, sensory block height (30 min after the initial bolus of local anesthetic), presence of motor block (30 min after the initial bolus of local anesthetic), number of top-up doses required during labor and incidence of postural headache.ResultsOut of the 140 recruited patients, 135 were retained for analysis. Compared with their 27-gauge counterparts, 25-gauge pencil point spinal needles provided a 1.6 min shorter DPEA onset (95% CI of the difference of the means: −3.2 to −0.1 min). However, there were no intergroup differences in terms of S2 block, sensory block height, motor block, number of top-up doses and incidence of postural headache.ConclusionDural puncture epidural analgesia with 25-gauge pencil point spinal needles provides a 1.6 min shorter onset time than DPEA with 27-gauge spinal needles. Although statistically significant, such a difference may not be clinically relevant. Further investigation is required to compare 25-gauge and 27-gauge spinal needles for DPEA in the setting of different local anesthetic infusion strategies.Trial registration number NCT03389945.

Isolated vasculitis involving the bladder is rare. We describe a case of irritative voiding and hematuria with slightly elevated inflammatory parameters. In order to exclude a neoplastic process we performed cystoscopy and computed tomography. Secondary systemic causes such as lupus erythematosus or rheumatoid arthritis were excluded. Cytopathological examination of the biopsies showed necrotizing vasculitis of the small bladder vessels, which responded to treatment with steroids and cyclophosphamide.

Supporting homeostasis in a pregnant woman with brain death to achieve fetal viability is called somatic support. We present a case of young pregnant woman at 21 weeks' gestation who developed acute respiratory distress syndrome secondary to influenza A H2N3 infection requiring veno-venous extracorporeal membrane oxygenation (VV ECMO) support for refractory hypoxemia. The clinical course was complicated by intracranial hemorrhage and subsequent brain death. After multidisciplinary team discussion with her family, consensus was reached to continue somatic support with VV ECMO to enable fetal development to attain extrauterine viability. The challenging clinical, ethical, and legal concerns are discussed.

A 22-year-old pregnant woman was seen at 14 weeks of pregnancy for infective endocarditis with a vegetation of 15 mm and wide mobility, which affected the native mitral valve accompanied by severe valvular insufficiency. Antibiotic treatment was given for 4 weeks despite the embolism risk. Due to persistence of vegetation size and after considering the fetal and maternal risk, the surgical procedure was favored. We decided to perform valvuloplasty and removal of lesion at 18 weeks of pregnancy. Fetal protection techniques were used and a bioprosthesis was placed before attempting a repair. The postoperative follow-up was satisfactory, achieving a successful birth by cesarean section at 30 weeks.
