Postoperative Pain

Brief summary

Thoracic surgery is one of the surgeries where postoperative pain is intense. In this study, the investigators aimed to compare the efficacy of two different intrathecal morphine doses administered for postoperative analgesia according to patients' ideal body weight.

Detailed description

Patients who underwent video-assisted thoracic surgery were divided into two groups: 10 mcg/kg and 7 mcg/kg intrathecal morphine for postoperative analgesia. Intraoperative and postoperative hemodynamic variables, postoperative morphine consumption, postoperative pain scores, side effects and additional analgesic requiretment were recorded.

Interventions

DRUGMorphine

In the literature, intrathecal morphine doses were applied according to the patients' actual body weight and there is no study comparing intrathecal morphine dose in thoracic surgery patients.

Design outcomes

Primary

MeasureTime frameDescription
pain scoresChange from baseline pain scores at 24 hoursPostoperative pain scores of the patients were recorded via Visual Analog Scale (VAS; 0= no pain, 10= worst pain)
morphine consumptionChange from baseline morphine consumption at 24 hoursAt the end of surgery, patients were allowed to use the patient controlled analgesia (PCA) device. The PCA delivered bolus doses of morphine (0.02 mg/kg) every 10 minutes without a backround infusion. Morphine consumption (mg) was evaluated and recorded postoperative 24 hours.

Secondary

MeasureTime frameDescription
diastolic arterial blood pressurechange from baseline diastolic blood pressure at 150 minutesIntraoperative diastolic arterial blood pressure (mmHg) values were recorded during surgery.
heart ratechange from baseline heart rate at 150 minutesIntraoperative heart rate (beats/minute) values were recorded during surgery.
side effectspostoperative 24 hoursAll of patients were visited in the thoracic surgery ward after surgery and side effects were evaluated and recorded.
mean arterial blood pressurechange from baseline mean arterial blood pressure at 150 minutesIntraoperative mean arterial blood pressure (mmHg) values were recorded during surgery.
systolic arterial blood pressurechange from baseline systolic blood pressure at 150 minutesIntraoperative systolic arterial blood pressure (mmHg) values were recorded during surgery.
