Randomized Controlled Trial Clinical TrialIntravenous but not perineural clonidine prolongs postoperative analgesia after psoas compartment block with 0.5% levobupivacaine for hip fracture surgery.
We evaluated the systemic and local effects of clonidine as an analgesic adjunct to psoas compartment block (PCB) with levobupivacaine. In a randomized, prospective, double-blind trial, 36 patients requiring hip fracture surgery received PCB and general anesthesia. Patients were randomized into three groups. ⋯ The groups were similar in terms of 24 h cumulative morphine and acetaminophen consumption. There were no significant differences among groups regarding postoperative adverse effects (bradycardia, hypotension, sedation, and nausea). We conclude that IV but not perineural clonidine (1 microg/kg) prolongs analgesia after PCB without increasing the incidence of adverse effects.

Randomized Controlled Trial Comparative Study Clinical Trial0.2% ropivacaine with or without sufentanil for patient-controlled epidural analgesia after anterior cruciate ligament repair.
The aim of this prospective, randomized, double-blind study was to evaluate the effects of adding 0.5 microg/ml sufentanil to 0.2% ropivacaine for patient controlled epidural analgesia (PCEA) on the quality of postoperative pain control in patients undergoing anterior cruciate ligament (ACL) reconstruction. ⋯ Adding 0.5 microg/ml sufentanil to 0.2% ropivacaine for patient controlled epidural analgesia improved pain control at rest but did not result in significant improvement of postoperative analgesia during continuous passive mobilization.

Postoperative, incisional pain is a unique but common form of acute pain. Because effective postoperative analgesia reduces morbidity following surgery, new treatments continue to be sought. It is through the development of investigational models and studies of the mechanisms that perioperative medicine can be advanced. This article reviews studies on a rat plantar hindpaw model for postoperative pain and proposes mechanisms for enhanced excitability of sensory neurons caused by incisions.

ReviewConsequences of inadequate postoperative pain relief and chronic persistent postoperative pain.
Inadequately controlled pain has undesirable physiologic and psychologic consequences such as increased postoperative morbidity, delayed recovery, a delayed return to normal daily living, and reduced patient satisfaction. Importantly, the lack of adequate postoperative pain treatment may lead to persistent pain after surgery, which is often overlooked. Overall, inadequate pain management increases the use of health care resources and health care costs. This article reviews the physiologic and psychologic consequences of inadequately treated pain, with an emphasis on chronic persistent postoperative pain.

ReviewMultimodal analgesia techniques and postoperative rehabilitation.
The concept of multimodal analgesia involves the use of different classes of analgesics and different sites of analgesic administration to provide superior dynamic pain relief with reduced analgesic-related side effects. Although multimodal analgesia techniques have assumed increasing importance in the management of perioperative pain, it has become increasingly apparent that postoperative outcome may not be improved. Nevertheless, the integration of multimodal analgesia techniques with a multimodal and multidisciplinary rehabilitation program may enhance recovery, reduce hospital stay, and facilitate early convalescence.
