Comparative Study Clinical Trial Controlled Clinical Trial
Epidural morphine reduces the risk of postoperative myocardial ischaemia in patients with cardiac risk factors.
Perioperative myocardial ischaemia is a predictor of postoperative cardiac morbidity (PCM). Epidural anaesthesia and adequate perioperative analgesia have been shown to improve myocardial oxygen dynamics due to interruption of pain and sympathetic pathways. The aim of the present study was to compare the incidence of ischaemia after either general anaesthesia followed by parenteral analgesia with morphine or combined epidural/general anaesthesia followed by analgesia with epidural morphine. ⋯ Forty-two percent of ischaemic episodes were associated with a heart rate > 100 bpm, or an increase of 20% over the baseline heart rate. We conclude that epidural anaesthesia/analgesia reduces but does not eliminate the risk of myocardial ischaemia and tachyarrhythmia. We were unable to determine any associated reduction in the risk of PCM.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of three morphine regimens in postsurgical patients using patient-controlled analgesia.
To compare the efficacy and toxicity of three patient-controlled analgesia (PCA) morphine regimens. ⋯ No significant differences in the efficacy or toxicity of the three morphine PCA regimens were identified.

Interpleural analgesia offers effective postoperative pain control and can enhance patient participation in pulmonary care regimens. Nurses play a vital role in the management of these patients by assisting with interpleural analgesia administration and monitoring patient outcomes.

Epidural analgesia has been associated in previous research with an increase in maternal temperature. ⋯ Epidural analgesia is associated with an increase in maternal temperature during labor and possibly with an elevation of newborns' first temperatures.
