Insights

Glycerin laxatives may help preterm infants pass meconium and achieve enteral feeding faster, but evidence on preventing feeding intolerance remains inconclusive for premature neonates.

Area of Science:

  • Neonatal Medicine
  • Pediatric Gastroenterology
  • Clinical Pharmacology

Background:

  • Glycerin laxatives are commonly used in neonates for meconium evacuation and to support enteral feeding.
  • Systematic review of glycerin laxative effectiveness in this population is lacking.

Purpose of the Study:

  • To evaluate the efficacy of glycerin enemas or suppositories in preventing feeding intolerance.
  • Focus on preterm infants born at or before 32 weeks' gestational age or weighing ≤1500 g.

Main Methods:

  • Comprehensive literature search across major databases (Medline, Embase, Cochrane, Scopus, Web of Science).
  • Inclusion of studies assessing glycerin for feeding intolerance in the target neonatal group.
  • Quality and evidence level assessment using the AHA's adapted Evidence Evaluation Worksheet.

Main Results:

  • Two studies were included, examining meconium evacuation and feeding intolerance.
  • One study found no significant difference in meconium passage or time to full enteral feeds.
  • The other study indicated shorter times to meconium passage and full enteral feeding, with reduced sepsis rates in the glycerin enema group.

Conclusions:

  • Current evidence on the effectiveness of glycerin laxatives for improving feeding tolerance in preterm infants (≤32 weeks GA or ≤1500 g) is inconclusive.
  • Further research is needed to definitively establish the role of glycerin in neonatal feeding protocols.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Drugs Affecting GI Tract Motility: Other Laxatives

Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
Osmotic or saline laxatives, like magnesium hydroxide or milk of...

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Drugs Affecting GI Tract Motility: Bulk-Forming and Stimulant Laxatives

Laxatives enhance bowel movements and alleviate constipation. They augment the stool's bulk, stimulate intestinal muscle contractions, draw water into the intestines, or soften the stool. There are five key types of laxatives: bulk laxatives, stimulant laxatives, osmotic laxatives, stool softeners, and lubricant laxatives.
Bulk-forming laxatives, such as psyllium, methylcellulose, and polycarbophil, absorb water in the intestine, increasing stool bulk and promoting bowel movement. This makes...

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...
