RCT: Free Access to Water vs. Fasting Pre-Cesarean Reduces Vomiting and Increases Maternal Satisfaction
25 Mar, 2024 | 11:17h | UTCStudy Design and Population: This randomized controlled trial was carried out at the Obstetric Unit, Universiti Malaya Medical Center from October 2020 to May 2022. A total of 504 women scheduled for planned cesarean delivery under spinal anesthesia were randomized into two groups: 252 were allowed free access to water up until being called to the operating theater, and 252 were required to fast from midnight before the procedure. The study primarily aimed to evaluate the effects of these preoperative oral intake policies on perioperative vomiting and maternal satisfaction.
Main Findings: The results demonstrated significant benefits for the group with free access to water. Specifically, perioperative vomiting was observed in 3.6% of women with water access compared to 9.5% of those fasting, indicating a relative risk reduction. Maternal satisfaction scores were notably higher in the water access group, with median scores of 9 versus 5 for the fasting group. Additional findings included lower reports of thirst, fewer instances of preoperative intravenous hydration, reduced ketone presence in urine, and a lower average number of vasopressor doses needed. Significantly, 95.2% of participants in the water access group would recommend their regimen to a friend, compared to only 39.7% in the fasting group.
Implications for Practice: Allowing free access to water up until the time of surgery for women scheduled for cesarean delivery under spinal anesthesia significantly reduces the risk of perioperative vomiting and improves maternal satisfaction, without adversely affecting post-cesarean recovery or neonatal outcomes. These findings support revising current preoperative fasting guidelines to improve patient experience and potentially enhance clinical outcomes.

AHA Scientific Statement | Anesthetic care of the pregnant patient with cardiovascular disease
20 Feb, 2023 | 12:29h | UTCSummary: The AHA emphasizes the need for specialized cardio-obstetric anesthesiology care for pregnant patients with cardiovascular disease, involving a multidisciplinary team of obstetricians, cardiologists, anesthesiologists, and other specialists as needed. The approach includes preoperative evaluation, intraoperative management, and postoperative care to maintain maternal hemodynamic stability, optimize oxygen delivery to the fetus, and avoid factors that exacerbate cardiovascular disease. Vaginal delivery with effective neuraxial analgesia is the preferred mode of delivery, with cesarean delivery used for obstetrical indications or high-risk patients. Specific recommendations are also provided for the management of patients with different types of cardiovascular disease, including congenital heart disease, valvular heart disease, pulmonary hypertension, and hypertrophic cardiomyopathy.
