Management of Post-Liquid Vomiting in Grade 2 Caustic Injury
Stop oral/liquid intake immediately and switch to enteral feeding via feeding jejunostomy or total parenteral nutrition, as persistent vomiting on day 5 indicates either delayed gastric emptying from gastric injury or early stricture formation that prevents adequate oral tolerance. 1
Immediate Actions
The vomiting one hour after liquid intake on day 5 signals that this patient cannot tolerate oral feeding despite the absence of pain. This is a critical warning sign that requires nutritional route modification.
Why Oral Feeding Failed
In Grade 2 caustic injuries affecting both esophagus and stomach:
- Pain during deglutition, hyper-salivation, and early dysphagia may hinder early oral intake 1
- The gastric caustic injury is likely causing delayed gastric emptying or early pyloric/antral involvement
- Grade 2b injuries carry >80% risk of stricture formation, which may already be developing 1
Nutritional Support Strategy
Switch to feeding jejunostomy or long-term parenteral nutrition immediately 1. The guidelines are explicit:
- "If symptoms persist, nutritional support by long-term parenteral nutrition or feeding jejunostomy is required" for Grade IIb CT esophageal injuries 1
- "Enteral feeding by nasogastric tubes or jejunostomy construction is recommended in patients unable to eat" 1
Do NOT continue attempting oral liquids - this risks aspiration, malnutrition, and delays healing. The nasogastric tube already in place is insufficient for this patient since she's vomiting through it.
Clinical Monitoring Required
While maintaining nil per os status and alternative nutrition:
Obtain repeat CT scan to assess for:
- Evolution to transmural necrosis (though unlikely on day 5 if stable)
- Early stricture formation
- Gastric outlet obstruction 1
Monitor for deterioration signs:
- Increasing abdominal pain
- Rebound tenderness
- Shock
- Laboratory derangements (renal failure, acidosis, leukocytosis) 1
Any clinical deterioration warrants immediate repeat CT and surgical consultation 1.
Timeline for Oral Reintroduction
Do not attempt oral feeding again until 3-6 weeks post-ingestion 1. The guidelines state:
- "Oral nutrition is usually well tolerated and should be introduced as soon as pain diminishes and patients can swallow" - but this patient has demonstrated she cannot swallow/tolerate liquids 1
- Endoscopic dilation for strictures should only be attempted 3-6 weeks after ingestion 1
Follow-up Planning
- Schedule 4-6 month post-ingestion endoscopy as most strictures develop within this timeframe for Grade II injuries 1
- Mandatory psychiatric evaluation before hospital discharge given the phenol poisoning context 1
- Prepare patient/family for likely need for endoscopic dilation procedures (3-5 sessions typically required) 1
Critical Pitfall to Avoid
Do not persist with oral/NG feeding attempts when vomiting occurs - this is a common error that leads to aspiration pneumonia, malnutrition, and delayed healing 2. The evidence shows that when enteral nutrition via NG tube causes vomiting in caustic injury patients, alternative routes (jejunostomy or TPN) must be instituted immediately 1.
