Effect of Low Fresh Gas Flows on Intraoperative Hypothermia Among Neonates Undergoing Abdominal Surgeries: A Randomized Controlled Trial
Authors' conclusion
Low-flow anesthesia technique at 1 L/min is a safe and effective approach for reducing the incidence and duration of intraoperative hypothermia in neonates undergoing abdominal surgery.
Study context
- Population
- Neonates scheduled for elective or emergency abdominal surgery
- Participants
- 160 neonates
- Comparison
- Low-flow vs routine-flow anaesthesia
- Primary endpoint
- Incidence of intraoperative hypothermia (core temperature < 36°C)
Primary result
As reported in the abstract
P = 0.01
Secondary outcomes
Drop in core temperature from baseline
P < 0.001
Minimum core temperature
P < 0.001
| Outcome | Group L | Group C | P value |
|---|---|---|---|
| % surgical time under hypothermia (< 36°C) | 50.3% (95% CI 43.3–57.3) | 65.6% (95% CI 58.6–72.6) | P = 0.003 |
Extubation time, inotrope use, hypoxia incidence
- Comparable between groups
Safety
Intraoperative blood loss
- Slightly higher in the low-flow group; clinical impact minimal
