Background: anesthesia with subarachnoid Morphine is not very used to alleviate acute postoperative pain during either elective or emergency surgical interventions. Objective: to describe cardiorespiratory repercussion of anesthesia with subarachnoid Morphine in patients who have undergone surgery. Methods: a longitudinal prospective descriptive study was conducted in a random sample of 500 patients who underwent surgery in the Surgical Service of Military Hospital of Holguín during the period from August 2009 to October 2012, who received subarachnoid anesthesia with 150 mg of hyperbaric lidocaine and 0.4 mg of lyophilized morphine. Variables such as systolic and diastolic blood pressures, cardiac frequency, respiratory frequency, oxygen saturation of hemoglobin, intensity of postoperative pain, time of postoperative analgesia, doses of rescue analgesia and adverse effects were monitored. Results: The mean time of postoperative analgesia was prolonged to more than 30 hours and the majority of patients didn't demand rescue analgesia during the first 48 hours. Pruritus, nausea, and vomiting predominated as adverse effects. Conclusions: The significant extension of analgesia with scarce demand of rescue analgesia and a stable cardiorespiratory behavior with an incidence of minor adverse effects convert anesthesia with subarachnoid Morphine into a useful and safe method for patients who have undergone either elective or emergency surgery.
