Effect of different gastrointestinal decompression methods during general anesthesia: a randomized controlled trial
Authors' conclusion
Under general anesthesia with drainage LMA ventilation, gastrointestinal decompression with a gastric tube placed through the LMA drainage port could effectively prevent flatulence and reduce the incidence of adverse reactions such as nausea and vomiting.
Study context
- Population
- ASA I–II patients aged 18–70 years undergoing gynecological surgery with laryngeal mask airway (LMA) ventilation under GA
- Participants
- 60 patients
- Comparison
- S vs G
- Primary endpoint
- Incidence of postoperative flatulence, nausea and vomiting, and other adverse reactions
- Follow-up
- 1, 6, and 24 h after surgery
Primary result
As reported in the abstract
Nausea and vomiting, and flatulence · 1 and 6 h after surgery
- Incidence of nausea and vomiting, and flatulence significantly increased in S vs G at 1 and 6 h
- S vs G: P < 0.05
Further findings
| Outcome | P value |
|---|---|
| Antral area (ultrasound) · after surgeryIncreased significantly in group S | P < 0.05 |
Nausea and vomiting, and flatulence · 24 h after surgery
- No significant difference between the two groups
Safety
Sore throat and hoarseness · three time points after surgery
- No significant difference between the two groups
