Antídoto para intoxicación por etilenglicol o metilenglicol

(Perlas)

Continue irrigation for 15 minutes or until each eye has been irrigated with at least 1 L of solution.

If the toxin is an acid or a base, check the pH of the tears after irrigation, and continue irrigation until the pH is between 6 and 8.

B. Gastric Lavage

Gastric lavage is more effective for liquid poisons or small pill  fragments  than  for  intact  tablets  or  pieces  of  mushroom.  It  is  most  useful  when  started  within  60  minutes after ingestion.

However, the lavage procedure may delay administration  of  activated  charcoal  and  may  stimulate vomiting  and  pulmonary  aspiration  in  an  obtunded patient.

1.  Indications—Gastric  lavage  is  sometimes  used  after

very  large  ingestions  (eg,  massive  aspirin  overdose), 

for collection and examination of gastric contents for identification  of  the  poison,  and 

make  it  easier  to  administer charcoal and oral antidotes.

2. Contraindications—Do not use lavage for stuporous or comatose patients with depressed airway protective reflexes

unless they are endotracheally intubated beforehand.

Some authorities advise against lavage when caustic material has been ingested; others regard it as essential to remove liquid corrosives from the stomach.

1.  Indications—Whole  bowel  irrigation  is  particularly effective for massive iron ingestion in which intact tablets are visible on abdominal radiographs. It has also been used for  ingestions  of 

lithium,  sustained-release  and  entericcoated tablets, and swallowed drug-filled packets.

2. Contraindications—Do not use in patients with suspected intestinal obstruction. Use with caution in patients who are obtunded or have depressed airway protective reflexes.
