Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of midwife top-ups, continuous infusion and patient-controlled epidural analgesia for maintaining mobility after a low-dose combined spinal-epidural.
We studied 133 women given a combined spinal-epidural for analgesia in labour. The initial intrathecal dose contained bupivacaine 2.5 mg with fentanyl 25 micrograms. When the mothers were comfortable, they were allocated randomly to one of three groups: continuous infusion (group Cl, n = 46), midwife top-ups (group MW, n = 43) or patient-controlled epidural analgesia (group PCEA, n = 44), to maintain analgesia throughout labour. ⋯ Four hours after combined spinal-epidural analgesia, 88.1% of women could SLR in group MW, 83.7% in group PCEA and 57.8% in group Cl (P = 0.002). Total use of bupivacaine was highest in group Cl (mean 11.3 (SD 3.3) mg h-1) compared with group MW (7.5 (3.1) mg h-1) and group PCEA (9.1 (2.1) mg h-1) (P < 0.001). Analgesia was similar between groups and overall satisfaction was equally high.

Randomized Controlled Trial Clinical Trial
Preoperative PCA teaching program to manage postoperative pain.
Patient-controlled analgesia (PCA) therapy was designed to provide patients with greater control in managing their pain. However, many patients continue to suffer from moderate to severe pain due to lack of knowledge about how to use PCA therapy. The results of this quasi-experimental study demonstrated that patients who received structured preoperative teaching had statistically significant higher knowledge regarding the use of PCA therapy and more positive attitudes toward using pain medicine. Patients who received the video teaching reported better pain control and satisfaction with pain management 4 and 8 hours following their surgical procedures.

Comparative StudyEpidural analgesia reduces the release of amino acids from peripheral tissues in the ebb phase of the metabolic response to major upper abdominal surgery.
The purpose of this prospective cohort study was to compare metabolic effects of epidural or patient controlled analgesia (PCA) in patients undergoing major upper abdominal surgery. Seventeen patients undergoing major upper abdominal surgery were included: 10 received perioperative epidural analgesia (Group I) and the remainder received morphine via a PCA device for postoperative analgesia (Group II). A number of measures compared between one day preoperatively (day 1) and day 2 postoperatively included femoral arterial and venous blood concentrations of glucose, lactate, pyruvate and amino acids. ⋯ The efflux of glycine, methionine, amino benzoic acid, alanine, and lysine was less in Group I than Group II on day 2 (P < 0.05). There was a significant difference in the total amino acid flux on day 2 (Group I = -1.2 mumol. (100 ml tissue)-1.min-1 cf Group II = -2.5 mumol. (100 ml tissue)-1.min-1; P = 0.04). In conclusion, perioperative epidural analgesia was associated with a reduced postoperative amino acid efflux two days following major upper abdominal surgery.

Advancements in intensive care therapy have progressed rapidly over the last two decades. Associated with this have been scientifically unsubstantiated sedation and analgesia practices in the intensive care unit. ⋯ In an analysis of the literature, we have attempted to present a practical approach to sedation and analgesia practices in the critically ill patient. The aim is to present a framework upon which medical personnel managing critically ill patients can develop a strategy for their own circumstances.
