Insights
Postoperative gastric decompression via orogastric tube does not reduce vomiting after tonsillectomy in pediatric patients. This study found no significant difference in vomiting incidence or complications between decompressed and non-decompressed groups.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Anesthesiology
Background:
- Vomiting is a common complication following tonsillectomy in pediatric patients.
- Postoperative gastric decompression is a potential intervention to mitigate this issue.
Purpose of the Study:
- To evaluate the effectiveness of postoperative gastric decompression in reducing vomiting and its associated complications after tonsillectomy.
Main Methods:
- A prospective, randomized controlled study involving 74 pediatric patients undergoing tonsillectomy.
- The intervention group received postoperative gastric aspiration with an orogastric tube, while the control group did not.
- Outcomes measured included vomiting incidence, episodes, volume, length of stay, antiemetic use, and readmissions.
Main Results:
- No statistically significant differences were observed between groups for vomiting incidence (74% vs. 85%), mean episodes, emesis volume, or postoperative length of stay.
- Rescue antiemetic use was similar (34% vs. 33%).
- Unplanned admissions for vomiting showed no significant difference (9% vs. 15%).
Conclusions:
- Postoperative gastric aspiration does not appear to decrease the incidence or complications of vomiting following tonsillectomy in pediatric patients.
- Current evidence suggests this intervention is not effective in this surgical context.
Objective:
To determine the effectiveness of postoperative gastric decompression in reducing the incidence and complications associated with vomiting following tonsillectomy.
Design:
A prospective, randomized controlled study.
Setting:
Private office and clinic of a university teaching hospital and research center.
Patients:
Eighty pediatric patients ranging in age from 22 months to 11 years, American Society of Anesthesiologists class I or II, undergoing tonsillectomy with or without adenoidectomy were enrolled in the study. Six were excluded from the final analysis, 5 because of failure of the parents to complete and return the data forms and 1 because of postoperative bleeding. Of the 74 patients included in the study, 35 were in the control group and 39 were in the study group.
Interventions:
The 39 patients in the study group underwent postoperative aspiration of gastric contents with an orogastric tube placed under direct visualization while the patient was still under general anesthesia. The 35 patients in the control group did not undergo gastric aspiration following surgery.
Main Outcome Measures:
The incidence of vomiting, the number of episodes of vomiting before and after hospital discharge, the total volume of emesis, the postoperative length of stay, the need for rescue antiemetic prophylaxis, and the number of readmissions to the hospital for persistent vomiting were noted.
Results:
No statistically significant difference (P<.05) was noted between the control group and the study group for the percentage of patients experiencing vomiting (74% vs 85%), the mean number of episodes of vomiting before (2.6 vs 2.8) and after (0.8 vs 0.7) hospital discharge, the mean volume of emesis (157 mL vs 222 mL), the postoperative length of stay (394 minutes vs 334 minutes), the percentage of patients requiring rescue antiemetics (34% [12 patients] vs 33% [13 patients]), and the percentage of unplanned admissions because of vomiting (9% [3 patients] vs 15% [6 patients]).
Conclusion:
Our results indicate that gastric aspiration does not decrease the incidence of vomiting following tonsillectomy.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
