In this study, the effect of perioperative uses of low dose ketamine on post-operative wound pain and analgesic consumption in patients undergoing elective Cesarean section was evaluated
Thoracotomy is associated with severe pain. Large doses of morphine can depress respiratory drive and compromise hemodynamic stability. Ketamine reduces hyperalgesia, prevents opioid tolerance and resistance and lowers morphine consumption. At sub-anesthetic (≤500g/kg) doses, ketamine rarely produces undesirable hemodynamic alterations. We hypothesized that by combining a sub-anesthetic dose…
Ketamine, an N-methyl-d-aspartate antagonist, blunts central pain sensitization at sub-anesthetic doses (0.3 mg/kg or less) and has been studied extensively as an adjunct for perioperative analgesia. At sub-anesthetic doses, ketamine has a minimal physiologic impact though it is associated with a low incidence of mild psychomimetic symptoms as well as nystagmus and double vision. Contraindic…
