Comparison of intrathecal morphine plus PCA and PCA alone for post-operative analgesia after kidney surgery.

OBJECTIVE: To study the use of intrathecal morphine plus PCA for reducing morphine consumption, pain scores, and improving patient-satisfaction. MATERIAL AND METHOD: The authors included patients who had received a flank incision for elective kidney surgery. The patients were random into the intrathecal and control groups by block randomization using the sealed envelop technique. The intrathecal group received 0.3 mg of intrathecal morphine before general anesthesia. Patients and providers were not apprised of the treatment. After the operation, both groups received morphine in a PCA pump. Morphine consumption, numeric rating score (NRS, range 0-10) at rest and while coughing, sedation score, nausea vomiting score, and itching score were evaluated at 1, 2, 6, 12, 24, and 48 hr. Patient satisfaction for pain control was recorded. RESULTS: The authors enrolled 80 patients in the present study. Demographic data was comparable between groups. The intrathecal group had less cumulative morphine consumption (p-value < 0.001), less NRS at rest (p-value < 0.001) and while coughing (p-value < 0.001) than the control group. The intrathecal group had a greater itching score than the control group (p-value < 0.001). The sedation score and patient satisfaction for pain control were not significantly different between groups (p-value = 0.55). CONCLUSION: Intrathecal morphine plus PCA could reduce morphine consumption and improve the analgesic effect over PCA alone postoperatively. Itching was more common in the intrathecal group. Overall, patient satisfaction for pain control was not improved.

Knowledge and skill after brief ACLS training.

OBJECTIVES: To determine the knowledge level and skill base in nurse anesthetists before and after brief ACLS training, and again three months later. METHOD: Thirty nurse anesthetists were tested for knowledge and skill before ACLS training comprising 1-hr lecture and handout, and 1-hr simulation training. Concepts included ABCD, primary and secondary survey, management, medications, and algorithms for common problems. Skill practice comprised airway management, chest compression and practice with equipment. After the training, the nurse anesthetists were immediately tested and again three months later. RESULTS: Age of participants averaged 39.33 + or - 3.14 years and working experience 10.04 +/- 3.23 years. The knowledge and skill scores pre- vs post-training vs three-months-later was 50.32 +/- 15.24 vs 75.40 +/- 10.29 (p < 0.001) vs 60.48 +/- 11.80 (p < 0.001) and 65.00 + 16.07 vs 79.67 +/- 10.80 (p < 0.001) vs 75.67 +/- 14.53 (p < 0.001), respectively. The pre-training vs three-months-post-training skill scores was not statistically different (p = 0.255). CONCLUSION: After the briefACLS training knowledge and skills were significantly improved, but knowledge was not retained at the post-training test levels until the 3-month check, albeit skills had persisted. More frequent ACLS education is necessary.
