Background: This experimental study was designed to investigate and compare the effects of different anesthesia techniques on rat cremaster muscle flap microcirculation.
Methods: Fifty male Sprague-Dawley rats (130-150 g body weight) were divided into five experimental groups containing ten animals each. Group I, group II, and group III were designated as inhalation, epidural, and spinal anesthesia groups, respectively. Group IV was designated as a combination group for inhalation and epidural anesthesia. Group V was a combination group of inhalation and spinal anesthesia.
Results: Group III and group V showed significant increases in the number of rolling and sticking leucocytes and in RBC volume (peripheral stasis) when compared with group I. Blood flow and velocity significantly increased without peripheral stasis in groups II and IV when compared with group I. Although there was no statistically significant difference in the numbers of rolling, sticking, and transmigrating leucocytes or in functional capillary perfusion, group IV had better flow hemodynamics in the peripheral microcirculation when compared with group I.
Conclusions: The inhalation and epidural anesthesia combination was determined to be the ideal anesthesia technique for improved peripheral microcirculation. Spinal anesthesia, either separately or in combination with inhalation anesthesia, has adverse effects on microcirculation.

Introduction: The neuraxial morphine has been regarded as the gold standard for postpartum analgesia. However, the recent advancements in patient-controlled analgesia and various regional nerve blocks have led to the implementation of multimodal analgesia strategies, which aim to reduce opioid usage and associated complications while ensuring satisfactory pain relief. The objective of this research is to investigate the optimal dosage of epidural morphine for alleviating moderate and severe pain after caesarean sections in healthy parturients, as well as reducing unnecessary burden of respiratory monitoring resources.

To avoid inhalational anesthetics, total intravenous anesthesia (TIVA) is required in patients with a predisposition to malignant hyperthermia (MH). However, propofol, which is frequently used, may be avoided in patients with egg allergies because of the contraindications in the drug information. Furthermore, some patients may not consent to the use of propofol.

Current guidelines for managing pulmonary arterial hypertension (PAH) in pregnancy recommend the use of PAH-specific medications, including phosphodiesterase type-5 inhibitors, calcium channel blockers, and prostacyclin analogs. However, there is limited consensus on the optimal agents and routes of administration during delivery. This case report describes a 24-year-old gravida 3 para 1 with Group I PAH, admitted at 29 weeks' gestation, for a planned cesarean delivery at 30 weeks gestation.

Study Objective: Nitrous oxide affects memory and recall. We aimed to determine if using nitrous oxide during labor affected patients' ability to learn and recall the risks and benefits of neuraxial analgesia.
Design: Single-center, prospective cohort study.
