Enemas serve various medical purposes, from surgical preparation to treating constipation. However, their effectiveness and necessity can vary depending on the specific application. Recent research suggests that while enemas can be beneficial in certain contexts, such as reducing postoperative complications in thoracic surgery, they may not provide significant advantages in other scenarios, such as preoperative preparation for cesarean sections or routine use during labor. Therefore, the decision to use enemas should be based on individual patient needs and specific clinical situations.
Enemas are a common medical procedure used for various purposes, including bowel preparation for surgeries and diagnostic tests, treatment of constipation, and as a delivery method for medications. This article explores the different aspects of enemas, their effectiveness, and their applications based on recent research findings.
Types of Enemas
Isoosmolar, Hyperosmolar, and Hypoosmolar Enemas
Enemas can be classified based on their osmolarity. A study comparing isoosmolar, hyperosmolar, and hypoosmolar enemas found that isoosmolar enemas demonstrated better gastrointestinal distribution and safety. Hyperosmolar enemas caused sloughing of the colonic epithelium, while hypoosmolar enemas had higher mucosal permeability3.
Enemas in Surgical Preparation
Barium Enema Preparation
The preparation for a barium enema can be influenced by the patient’s desire for control and previous experience with the procedure. Providing patients with a choice of preparation methods can be problematic for those with a high desire for control, potentially causing reactance1.
Preoperative Enemas for Cesarean Sections
Research indicates that preoperative enemas do not significantly impact the return of gastrointestinal function or reduce postoperative complications in elective cesarean sections. Studies found no significant differences in bowel sound time, flatus time, or length of hospital stay between patients who received enemas and those who did not2 9.
Enemas in Thoracic Surgery
In thoracic surgery, enemas have been shown to reduce postoperative abdominal distension and constipation. Patients who received enemas had significantly lower rates of these complications compared to those who did not10.
Enemas in Diagnostic Procedures
Colonoscopy Preparation
The addition of enemas to oral lavage preparation for colonoscopy does not improve the quality of bowel preparation or mucosal visualization. Moreover, patients who received both oral lavage and enemas reported higher rates of anorectal trauma and were more likely to refuse future preparations4.
Flexible Sigmoidoscopy
For flexible sigmoidoscopy, a single hypertonic phosphate enema administered one hour before the procedure is as effective as more complex regimens involving multiple enemas. This simpler approach is also more convenient and cost-effective8. Additionally, home-administered enemas are as effective as those administered in a hospital setting, offering a more comfortable and less embarrassing option for patients7.
Enemas for Constipation
Treatment of Rectal Fecal Impaction in Children
Enemas and polyethylene glycol (PEG) are equally effective in treating rectal fecal impaction in children. However, PEG is associated with higher rates of fecal incontinence, making enemas a viable first-line therapy for this condition6.
Enemas During Labor
Use During Labor
The routine use of enemas during labor does not significantly reduce puerperal or neonatal infection rates, nor does it shorten labor duration. Given the lack of clear benefits, routine enemas during labor are not recommended5.
