“…Excessive noise has been associated with impaired concentration 6 and verbal communication between staff members, both of which are essential to patient safety. 7 The Environmental Protection Agency (EPA) suggests a level up to 45 dB can interfere with concentration during the day. 2 The International Noise Council has stipulated that noise levels in intensive care units of hospitals should not exceed the mean level of 45 dB during the day and 35 dB at night.…”

Objective Intraoperative noise exposure has been associated with an increased risk of complications, communication errors, and stress among surgical team members. This study evaluates intraoperative noise levels in cesarean deliveries during different shift times, for example, night shifts, day shifts, and hand-off times between shifts. Study Design This is a secondary analysis of a prospective observational study which measured volume in decibels, percentage of time above safe levels (>60 dB), startle noise events (events with rapid increase of decibel level above baseline noise), and peak levels (>75 dB) for cesarean deliveries during a 3-month preintervention and postintervention study. This secondary analysis of noise data evaluated whether there were differences in noise for cases occurring during day shifts (6:31 a.m.–4:59 p.m.), night shifts (6:01 p.m.–5:29 a.m.), and hand-off times (5:30 a.m.–6:30 a.m. and 5:00 p.m.–6:00 p.m.). Correlates and postoperative complications during the respective shifts were additionally analyzed. Results Noise data were collected for a total of 312 cesarean deliveries; 203 occurred during the day shift, 94 during the night shift, and 15 during hand-off times. Median noise in decibels, median noise at various key intraoperative points, number of startle events, percentage of time above 60 dB, and above 75 dB had no significant differences throughout the various shift times. Significantly larger numbers of postpartum hemorrhages, unscheduled, urgent, and STAT cesarean deliveries occurred at hand-off times and on night shifts. Conclusion Noise levels during cesarean deliveries did not significantly vary when comparing night shifts, day shifts, and hand-off times, despite significantly higher numbers of urgent and STAT cases occurring overnight and during hand-off times. However, more than 60% of case time had noise levels exceeding those considered safe. This suggests that ambient background noise may be contributing more to overall noise levels rather than the specific clinical scenario at hand. Key Points

ObjectiveThis study sought to compare the risks and outcomes associated with category I cesarean section procedures performed in the delivery room versus those performed in the operating room.Patients and MethodsThe analysis included 126 singleton pregnant women who underwent inpatient delivery at the Second People's Hospital of Nanning between January 2021 and May 2024. Following propensity score matching, 21 cases were in the delivery room group, and 105 cases were in the operating room group. Parameters under investigation encompassed decision‐to‐delivery interval, incision‐to‐delivery interval, surgical duration, intraoperative blood loss, postoperative antibiotic duration, postoperative hospital stay length, postoperative fever incidence, adverse neonatal outcomes, and blood routine parameters.ResultsThe decision‐to‐delivery interval was significantly shorter in the delivery room group than in the operating room group. Conversely, the delivery room group exhibited longer surgical durations, higher blood loss, prolonged postoperative antibiotic usage, extended hospital stays, and elevated white blood cell counts with statistical significance (p < 0.05). Nevertheless, no notable variations were observed between the groups in maternal and neonatal outcome indicators, such as adverse neonatal outcomes and postoperative fever rates.ConclusionsThe outcomes suggest that the delivery room group showed increased risks compared with the operating room group, potentially indicating heightened vulnerabilities to bleeding and infection. Hence, it is advisable for patients to undergo surgery in the operating room unless the delivery room is equipped with sterile surgical facilities or in cases of urgent necessity.
