Randomized Controlled Trial
Significant analgesic effects of one session of postoperative left prefrontal cortex repetitive transcranial magnetic stimulation: a replication study.
In a recent preliminary trial in 20 patients after gastric bypass surgery, 20 minutes of repetitive transcranial magnetic stimulation (TMS) over the left prefrontal cortex was associated with a 40% reduction in postoperative patient-controlled morphine use. As is the case with all novel scientific findings, and especially those that might have an impact on clinical practice, replicability is paramount. This study sought to test this finding for replication and to more accurately estimate the effect size of this brief intervention on postoperative morphine use and postoperative pain and mood ratings. ⋯ Although more research is needed to verify these observed effects independently, findings from the original postoperative TMS trial were replicated. TMS may have the potential to significantly improve current standards of postoperative care among gastric bypass patients, and further studies may be warranted on other surgical populations. Future investigations should use methodology that permits more definitive conclusions about causal effects of TMS on postoperative pain (for example, double-blinding, sham stimulation that is matched with real TMS with respect to scalp discomfort).

To investigate if the addition of dexmedetomidine to meperidine in a patient-controlled analgesia (PCA) device would reduce postoperative meperidine consumption when compared with meperidine alone. ⋯ When compared with meperidine PCA, meperidine-dexmedetomidine PCA reduces postoperative meperidine consumption.

Effective treatment of perioperative acute pain requires that information about the patient's goals for pain relief, previous history with analgesics, and type of surgical procedure is used to guide decisions about analgesic regimens. Analgesics are selected based on the location of surgery, degree of anticipated pain, and patient characteristics (such as comorbidities), and routes of administration and dosing schedules are determined to maximize the effectiveness and safety of analgesia while minimizing the potential for adverse events. ⋯ To accomplish this, nurses must have a thorough understanding of the pharmacology of analgesics. This article provides useful information for commonly used analgesics, primarily nonsteroidal antiinflammatory drugs (NSAIDs), opioids, and local anesthetics for control of acute postoperative pain.

[Lactate as a predictor of mortality and multiple organ failure in patients with the systemic inflammatory response syndrome.].
The systemic inflammatory response syndrome (SIRS) is common in the postoperative period of critically ill patients. The objective of this study was to investigate the correlation between lactate level, multiple organ dysfunction, and mortality in patients with SIRS. ⋯ Patients with elevated lactate in the first 24 hours after the diagnosis of SIRS did not have more organic dysfunction than patients with normal lactate levels, but they had an increased risk of death in 7 days.

Postoperative nausea and vomiting (PONV) is one of the most distressing morbidities associated with surgery. Even though the incidence can be as high as 30% elsewhere no work has been done to assess the incidence in any health facility in Ghana. This study was carried out to find out the incidence, risk factors and the management of PONV in a tertiary healthcare facility. ⋯ Thirty-four percent of patients in the study had PONV indicating that the problem is not uncommon among post-surgical patients in KBTH. Awareness of the problem should be highlighted and adequate management should be given to all patients. Patients at risk should be identified and appropriate management instituted.
