In this study, doctors from the United States identified factors influencing postoperative IV analgesic use after colectomy.
The team retrospectively evaluated 481 patients who underwent colectomy between 1997 and 2000. They calculated the amount of postoperative IV narcotics needed in morphine equivalents.
The doctors found that of the procedures performed 10% were total/subtotal colectomies, 42% were right, 3% transverse, 40% left/sigmoid, and 4% low anterior resection.
A laparoscopic colectomy was performed in 11% of patients.

The mean postoperative morphine equivalent use was 160.2 mg.
The team determined that narcotic analgesic use was significantly less in women, in patients with a diagnosis of cancer, or who underwent laparoscopic colectomy.
Furthermore, patients undergoing a right colectomy required less postoperative narcotics than patients having other types of colectomies.
In addition, the team identified a positive correlation between postoperative narcotic use and operative time, and a negative correlation with patient age.
Linear regression analysis determined that age, female gender, and laparoscopy were independent predictors for decreased narcotic use.
Dr Charles Joels's team concluded, "Postoperative IV narcotic analgesic use is affected by gender, patient age, indication for colectomy, operative time, type of procedure, and operative technique".
