Associated factors with umbilical arterial pH after cesarean delivery under spinal anesthesia: a retrospective cohort study.

Background: Maximum decrease of blood pressure and number of minutes of hypotension were independently associated with umbilical arterial pH. However, the impact of hypotension considering the duration of it on umbilical arterial pH is unknown.

Methods: Pregnant women aged ≥ 20 years who delivered a baby at full-term via a cesarean delivery under a single-shot spinal anesthesia between January 2017 and March 2019 were included.

The ultrasound-guided nerve blocks of abdominal wall contributed to anesthetic management of cholecystectomy in a patient with Becker muscular dystrophy without using muscle relaxants.

Becker muscular dystrophy (BMD) is a progressive neuromuscular disorder caused by mutations in the dystrophin gene. The sensitivity to non-depolarizing muscle relaxant in a patient with muscle dystrophy is reportedly higher than that in normal individuals, and the duration of the effect is known to be prolonged. In this report, we present the case of a 58-year-old man with BMD who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis under total intravenous anesthesia without the use of muscle-relaxant drugs and supplemented with regional anesthesia.

[Effects of RSB and TAPB on Postoperative Pain in Laparoscopic Cholecystectomy].

Background: Several reports have examined meth- ods to control pain after a laparoscopic cholecystec- tomy (LC) and have shown regional anesthesia to be an effective method. We had been performing LC using simple general anesthesia (G); however, in 2013, we adapted a rectus sheath block (RSB), and in 2014, we used a combination of RSB and a subcostal transversus abdominis plane block (TAPB) on the right side. We report on the transition from G to regional anesthesia in LC and its effect on postoperative pain.

[Unilateral Thoracic Paravertebral Block for Effective Control of Pain : A Case Report of a Patient with Esophageal Cancer and Cirrhosis of the Liver.].

We report a case in which unilateral thoracic para- vertebral block was used to effectively control pain in a 78-year-old male patient with Child's A liver cirrhosis and esophageal cancer. Epidural anesthesia was con- sidered risky in this case because of the low platelet count from cirrhosis. Therefore, we performed a unilat- eral thoracic paravertebral block and cannulation under general anesthesia.
