Chronic pain often is frustrating to nurses and patients, since many times it has not been responsive to traditional medical approaches. The purpose of this article is to discuss the chronic pain syndrome and the role of nursing within a multidisciplinary chronic pain rehabilitation program designed to return the patient to a functional lifestyle. The purpose and rationale for each treatment modality within the pain management program is described, although the treatment plans are individualized for every patient. ⋯ Nurses collect data and continually assess the patient to develop comprehensive nursing care plans. In this intensive educational program, nurses also assist in teaching the patient positive health practices to control the pain. Further evaluations of these chronic pain rehabilitation programs are needed.

ReviewThe stress response to surgery: release mechanisms and the modifying effect of pain relief.
This short review updates information on the release mechanisms of the systemic response to surgical injury and the modifying effect of pain relief. Initiation of the response is primarily due to afferent nerve impulses combined with release of humoral substances (such as prostaglandins, kinins, leukotrienes, interleukin-1, and tumor necrosis factor), while amplification factors include semi-starvation, infection, and hemorrhage. The relative role of the various signals in producing the complex injury response has not been finally determined, but the neural pathway is probably most important in releasing the classical endocrine catabolic response, while humoral factors are important for the hyperthermic response, changes in coagulation and fibrinolysis immunofunction, and capillary permeability. ⋯ Systemic opiate administration, as well as non-steroidal antiinflammatory drugs, exert only a small modifying effect on the response. Low-dose combined analgesic regimens may provide total pain relief, but exert no important effect on the stress response. In summary, pain alleviation itself may not necessarily lead to an important modification of the stress response, and a combined approach with inhibition of the neural and humoral release mechanisms is necessary for a pronounced inhibition or prevention of the response to surgical injury.

Randomized Controlled Trial Comparative Study Clinical Trial[A combination of sufentanil and 0.25% bupivacaine administered epidurally for obstetrical analgesia. Comparison with fentanyl and placebo].
The study reported was designed to determine whether 15 micrograms sufentanil would provide analgesia comparable in duration and quality with that given by 75 micrograms fentanyl, when associated with plain 0.25% bupivacaine for extradural analgesia for labour. Patients (n = 124) in labour and at full term were randomly divided into 3 groups. Group 1 (n = 41) were given 12 ml of 0.25% plain bupivacaine with saline, group 2 (n = 41) 12 ml of 0.25% plain bupivacaine with 75 micrograms fentanyl and group 3 (n = 42) 12 ml of 0.25% plain bupivacaine with 15 micrograms sufentanil. 11 cases were excluded from the study (8 Caesarean sections, 3 technical failures). ⋯ The only side-effect seen with sufentanil and fentanyl was pruritus (group 2: 21.9%, p less than 0.05; group 3: 21.4%, p less than 0.05; group 1: 2.4%). These results showed that 15 micrograms sufentanil could replace 75 micrograms fentanyl for extradural pain relief of labour with plain 0.25% bupivacaine. However, the use of opioids with local anaesthetics would seem to be of interest only if labour is likely to be prolonged.

In recent years hospitals have begun to institute special postoperative pain services staffed by anesthesia department personnel. The charter for such services is to provide the best and most appropriate postoperative analgesia for surgical patients, in particular for the increasing numbers of patients who, released from hospital soon after surgery, still require pain relief on an outpatient basis. This review focuses on the relative benefits and risks of the currently available options for postoperative pain relief: intramuscular (i.m.) and intravenous (i.v.) administration of narcotics; epidural or subarachnoid administration of narcotics and/or local anesthetics; and peripheral nerve blocks with local anesthetics. In terms of efficacy, cost, risk, and personnel requirements, the particular advantages of continuous analgesia techniques--including patient-controlled analgesia--are discussed.
