The Effects of Local Anesthetics on Postoperative Pain

Abstract

This study was performed to determine if intraoperative local anesthesia improved control of postoperative pain after inguinal herniorrhaphy and to compare the effects of two commonly used local anesthetics on pain management. The Gate Control Theory of Pain formed the theoretical basis for this study. A retrospective nonexperimental study in an ex post facto design was used. Data were collected from 1990 through 1997 on 120 patient charts. The use of local anesthetic intraoperatively significantly decreased patients' lengths of stay postoperatively (P = 0.00) and need for postoperative narcotics (P = 0.00). Bupivacaine was found to be superior to lidocaine in decreasing the need for postoperative narcotic analgesia. Researchers concluded that many patients would benefit from intraoperative injection of local anesthesia. This information can affect patient care outcomes through decreasing recovery time, reducing postoperative pain, and reducing health care costs.

Randomized clinical trial comparing spinal anesthesia with local anesthesia with sedation for loop colostomy closure

“…Systemic complications also occurred in two patients in the other group: nausea (one) and psychomotor agitation (one), which may have been a collateral effect from midazolam (11) , but there was no statistical difference between the groups.…”

“…After the operation, the mean pain level was lower in the LA group during the first 6 hours, and there was a significant difference from the second hour onwards. According to Roberge and McEwen (11) , postoperative pain is also associated with the choice of local anesthetics. This conclusion came from a study in which they found that bupivacaine was important for obtaining low pain values.…”

Intraoperative wound infiltration with local anesthetic in open abdominal hysterectomy significantly reduces postoperative opioid consumption (wound infiltration)

“…U ovoj studiji korišćen je 0,25 % levobupivakain zato što ima duži poluživot nego lidokain, što produžava njegovo postoperativno analgetsko dejstvo. 17 Rezultat ovog istraživanja pokazuje da infiltracija rane sa 0,25% levobupivakainom pre hirurškog zatvaranja rane predstavlja bezbedan i efikasan metod za terapiju bola nakon klasične abdominalne histerektomije. Prosečna ocena prisustva i jači-ne bola tokom 24 sata nakon operacije bila je niža kako u mirovanju tako i tokom kašljanja.…”
