Training for the surgical management of postpartum hemorrhage: a multicenter survey of resident physicians.

BACKGROUND: To actively address maternal morbidity and mortality in Mexico, proficiency among obstetrics and gynecology (OBGYN) residents in the surgical management of postpartum hemorrhage (PPH) is a priority. However, the capacity of programs to provide this training is unknown. OBJECTIVE: The self-reported knowledge, education, and proficiency of common surgical techniques for the management of PPH among OBGYN residents in Mexico was evaluated. Educational resources, perceived barriers to acquiring skills, and clinical decision-making were explored. MATERIALS AND METHODS: In July of 2018, an anonymous electronic survey was sent to 86 residents at four hospitals throughout Mexico. Surgical techniques queried included uterine tamponade (UT), uterine compression sutures (UCS), uterine devascularization (UD), hypogastric artery ligation (HAL), and gravid hysterectomy (HT). Participants also answered case-based questions about a patient with PPH. RESULTS: The survey response rate was 59.3% (51/86). Seventy-nine percent of residents reported understanding the rationale and techniques for the surgical intervention of PPH. However, 43.9% reported limited ability to perform these procedures with autonomy. Eighty-six percent of residents reported exposure to these techniques while performing a rescue procedure during PPH and 49% reported learning these procedures while performing prophylactic techniques in patients without PPH. Only 25.5% had been exposed to simulation training. Lack of a training module for these skills in their curriculum was noted by 74.5%. The majority of the participants chose UCS, UD, HAL, and HT as the first, second, third, and fourth rescue procedures to perform for PPH, respectively. CONCLUSION: Most residents reported theoretical knowledge of surgical interventions for PPH, but their self-rated ability to independently perform such skills and a curriculum focused on PPH management was suboptimal.

The effect of patient-selected or preselected music on anxiety during cesarean delivery: a randomized controlled trial.

Background: Women undergoing cesarean delivery may have significant anxiety prior to surgery. Nonpharmacological approaches to anxiety reduction are favored in this patient population.Objective: The aim of this study was to determine the effects of patient-selected or preselected music on anxiety in parturients undergoing scheduled cesarean delivery.Materials and methods: This is a prospective, randomized controlled trial (IRB protocol #2015P002043; ClinicalTrials.gov, NCT02732964), of 150 parturients undergoing elective cesarean delivery. Parturients were randomized to patient-selected music (Pandora®), preselected music (Mozart), or no music (control). The primary outcome was anxiety after music exposure (versus no music) in the preoperative holding room. Secondary outcomes included postoperative anxiety, postoperative pain, and patient satisfaction.Results: Baseline anxiety and anxiety following preoperative exposure did not differ in the Pandora versus control group (3.8 ± 2.4 versus 4.6 ± 2.6, mean difference -0.8 [95% CI -1.8 to 0.2], p = .12), but was lower in the Mozart group versus control group (3.5 ± 2.5 versus 4.6 ± 2.5, mean difference -1.1 [95% CI -2.2 to -0.1], p = .03). Postoperative anxiety did not differ in the Pandora versus control group (1.0 ± 1.4 versus 1.3 ± 2.0, mean difference -0.3 [95% CI -1.0 to 0.4], p = .43), or in the Mozart versus control group (0.8 ± 1.3 versus 1.3 ± 2.0, mean difference -0.5 [95% CI -1.2 to 0.2], p = .15). Postoperative pain was not different in the Pandora group versus control group (0.8 ± 1.5 versus 1.4 ± 1.9, mean difference -0.6 [95% CI -1.3 to 0.1], p = .10), but was lower in the Mozart versus control group (0.6 ± 1.3 versus 1.4 ± 1.9, mean difference -0.8 [95% CI -1.4 to -0.1], p = .03). Total patient satisfaction scores were not different among the control, Pandora, and Mozart groups.Conclusion: While preselected Mozart music results in lower anxiety prior to cesarean delivery, patient-selected Pandora music does not. Further investigation to determine how music affects patients, clinicians, and the operating room environment during cesarean delivery is warranted.Clinical trial registration: NCT02732964.

Transient Tachypnea of Newborns Is Associated With Maternal Spinal Hypotension During Elective Cesarean Delivery: A Retrospective Cohort Study.

BACKGROUND: The risk for transient tachypnea of newborns, a common cause of respiratory distress in the neonatal period, is 2- to 6-fold higher during elective cesarean delivery compared to vaginal delivery. Here, we evaluated the association between transient tachypnea of newborns and the degree and duration of predelivery maternal hypotension during spinal anesthesia for elective cesarean delivery. METHODS: Demographic data, details of anesthetic management, blood pressure measurements, and vasopressor requirement preceding delivery were compared between transient tachypnea newborns (n = 30) and healthy neonates (n = 151) with normal respiratory function born via elective cesarean delivery between July 2015 and February 2016. The degree and duration of hypotension were assessed using area under the curve for systolic blood pressure (SBP) ≤90 mm Hg and area under the curve for mean arterial pressure ≤65 mm Hg. After adjusting for confounders, multivariable logistic regression was used to evaluate the association between area under the curve for SBP and transient tachypnea of newborns. RESULTS: The median area under the curve for SBP was higher in cases of transient tachypnea of newborns (0.94; interquartile range, 0-28.7 mm Hg*min) compared to healthy controls (0; interquartile range, 0-3.30 mm Hg*min; P = .001). Similarly, median area under the curve for mean arterial pressure was also higher in cases of transient tachypnea of newborns (0; interquartile range, 0-18.6 mm Hg*min) compared to controls (0; interquartile range, 0-1.1 mm Hg*min; P = .01). Mothers of transient tachypnea newborns received significantly higher amounts of phenylephrine and ephedrine compared to controls (P = .001 and 0.01, respectively). Hence, the total vasopressor dose given to mothers in the transient tachypnea of newborn group was much higher than for the control group (P = .001). In the multivariable logistic regression, area under the curve for SBP was significantly associated with transient tachypnea of newborns (odds ratio, 1.02; 95% CI, 1.01-1.04, P = .005) after adjusting for gravidity and the type of anesthetic (spinal versus combined spinal epidural). CONCLUSIONS: Our results suggest that the degree and duration of maternal SBP <90 mm Hg after neuraxial anesthesia during elective cesarean delivery are associated with transient tachypnea of newborns. Future prospective studies should further explore the effects of maternal hypotension, its prevention, and treatment for transient tachypnea of newborns.
