Postoperative pain management continues to be a challenge to health care professionals. To address this, hospitals across the country are developing Acute Pain Services. It is fast becoming a specialty area and is being incorporated into the realm of practice of anesthesiologists. As postanesthesia nurses, we are in a unique position to enter this new field.

Postoperative pain relief is often inadequate. Ignorance and misconceptions about opioids by ward staff contribute to this poor management. The introduction of acute pain teams has done much to improve pain relief for patients. It may also have contributed to changes in attitudes and knowledge of medical and nursing staff. We questioned 48 doctors and nurses on their knowledge and beliefs about postoperative pain relief. Staff members were questioned on two units, one with access to an acute pain team and one without. Over half those on the unit using traditional postoperative care thought patients did not receive adequate pain relief (58%). In comparison, only one respondent from the unit with the pain team thought this was the case (P < 0.001). More staff members that had experience of patient-controlled analgesia (PCA) were optimistic about its benefits than those in the unit with no experience; they were also less concerned about possible side effects. Only one respondent on the unit using PCA thought it carried a risk of drug dependence, compared to over half (55%) of those on the unit with no experience in this technique (P < 0.001). Over two-thirds of staff familiar with PCA thought nursing workload had decreased. Acute pain teams have an important role in educating ward staff. The impact of establishing such teams on staff knowledge and attitudes needs further study to ensure that they can carry out this role most effectively.

Postoperative pain is commonly treated with significant doses of narcotics, occasionally resulting in side effects including nausea, pruritus, and respiratory depression. One potential advantage of regional anesthesia is profound postoperative analgesia that reduces exposure to potent narcotics. To evaluate the efficacy of two long-acting local anesthetics, bupivacaine and etidocaine, in providing pain relief after major shoulder surgery, we randomized 20 patients to receive either bupivacaine or etidocaine for brachial plexus block as the primary anesthetic for shoulder surgery. Surgeons, patients, and the acute pain service were blinded as to drug selection. After the patient was sedated, an interscalene block was placed with the use of a nerve stimulator to facilitate proper needle placement. Forty milliliters of either 0.5% bupivacaine or 0.75% etidocaine containing 5 micrograms/mL epinephrine was injected into the brachial plexus sheath. An additional 8 mL of local anesthetic was administered for superficial cervical plexus blockade. Intraoperative sedation was accomplished with an intravenous infusion of methohexital as needed. After surgery, patients received a standard patient-controlled analgesia protocol providing incremental doses of morphine. The degree of postoperative analgesia resulting from residual local anesthetic effect was expressed as the time until first morphine requirement and the total dose of morphine required during the first 24 hours postoperatively. We found no statistically significant intergroup differences either in time of initial use of morphine or in the total dose of morphine required in the first 24 hours. Both etidocaine and bupivacaine provide prolonged analgesia after major shoulder surgery when injected into the brachial plexus. Bupivacaine, however, possesses significant cardiotoxicity and has a relatively delayed onset in peripheral neural blockade. Etidocaine is less cardiotoxic and also has a more rapid onset of effect. Thus etidocaine may be a preferable agent for interscalene block for major shoulder surgery.

Many articles in the literature document the fact that postoperative pain therapy has not improved for decades despite new insights into pain physiology, the availability of powerful analgesics and the development of new techniques. This project was set up to develop practical, effective, safe, and easy to run acute pain therapy. METHODS. Postoperative pain management had to be optimized according to the facilities available today. Therefore, the legal background is presented first. Second, several medical and organizational principles were chosen to serve as a basis for the new organizational structure: Continuously monitoring the patient's pain during the whole stay in hospital, Introduction of a simple verbal 4-point pain score for determination and documentation of pain allowing the nurses to differentiate pain that should be treated or not, A simple sedation score, Use of "balanced analgesia" and "pre-emptive analgesia", Drug administration according to the needs of the patient, Partial transfer of the responsibility for pain treatment to nurses. Plans and algorithms were expanded to allow nurses and anaesthesiologists to reach the previously determined goals. RESULTS. In a small study including 107 patients, it was demonstrated that the quality of pain treatment improved significantly. Furthermore, patients, nurses and physicians are much more content with the new pain treatment regimen. DISCUSSION. The difficulties in realizing such a concept are described. The importance of thorough teaching is underlined in a nurse-based system. However, it is not yet clear whether this pain treatment has resulted in reduced morbidity, reduced mortality and a shortened hospital stay of the patients.

Postoperative pain management in children has been subject to increasing interest during the last decade, but is still insufficient. A survey is presented concerning postoperative pain management in children. The value of monitoring the pain as well as the opioid side effects in children is stressed, and such methods are presented. Acute Pain Service is mentioned and the most important pharmacological aspects regarding non-steroidal anti-inflammatory drugs, paracetamol, opioids and local anaesthetics are discussed. The management of postoperative pain in neonates is reviewed separately. It is concluded that the present insufficient management of postoperative pain in children is not due to the lack of methods and techniques, but rather to lack of sufficient utilization and comprehension of the possibilities. Moreover, pain management in children should be individualised. It is also necessary to be more aware of side effects of the pharmacological treatment.

The incidence, magnitude, and duration of acute pain experienced by neurosurgical patients after various brain operations are not precisely known, because of a lack of well-designed clinical and epidemiological studies. We assessed these important pain variables in 37 consecutive patients who underwent various brain neurosurgical procedures. Postoperative pain was more common than generally assumed (60%). In two-thirds of the patients with postoperative pain, the intensity was moderate to severe. Pain most frequently occurred within the first 48 hours after surgery, but a significant number of patients endured pain for longer periods. Pain was predominantly superficial (86%), suggesting somatic rather than visceral origin and possibly involving pericranial muscles and soft tissues. Subtemporal and suboccipital surgical routes yielded the highest incidence of postoperative pain. Age and sex were significantly associated with the onset of pain, with female and younger patients reporting higher percentages of postoperative pain. Psychological Minnesota Multiphasic Personality Inventory profiles of patients with and without pain significantly differed on the Hypochondriasis scale, with patients without pain scoring unexpectedly higher than patients with pain. It is possible that hypochondriasis serves as a defense mechanism against pain, at least in some patients. Results of this pilot study indicate that postoperative pain after brain surgery is an important, although neglected, clinical problem, that deserves greater attention by surgical teams, to provide better and more appropriate treatment.

Nociception is a protective system of the body which prevents it from injury and tissue damage. Human beings respond to noxious stimuli by moving away. They learn by pain to avoid these situations in future. Shortly after major injury, there is a limited analgesic period allowing the body to flee the area of danger, later on, emerging pain compels the body to rest and supports recuperation. While acute pain has a certain meaning, chronic pain does not. It induces a comprehensive suffering including loss of initiative, appetite and vigilance. It reduces life-quality, often accompanied by depressive moods. Acute pain causes changes in the central nervous system leading to an increased sensitivity of nociception (hyperalgesia). During healing, the central processing of noxious stimuli is normalised taking minutes to weeks. Sometimes, unknown factors initiate chronification of pain. Changes on a molecular level in peripheral tissue as well as in the central nervous system induce "cellular early genes", a synthesis of c-fos, c-jun and other proteins favouring the chronification of pain. All efforts have to be made to depress or interrupt such a development. One of the first steps to pain prophylaxis in a hospital is an optimal surgical technique: incision, extension, limited tissue damage and minimal invasive surgery should guarantee the smallest impairment of the nociceptive system possible. However, nociceptive input is intense and of long duration and leads to central sensibilisation. Postoperative pain has lost its function as surgery anticipates healing. Pain induces a reduction of ventilation, circulation, digestion and increases the risk of other disorders. There is need of aggressive pain treatment for humanitarian reasons and for reasons of late sequelae like permanent pain and increased reduction of function. This is of pivotal importance in patients with amputations or sympathetic reflex dystrophy (SRD). Antinociception is best provided by regional anaesthesia technique with a combination of local anaesthetics and opioids which results in better outcome. Hence, regional anaesthesia techniques are strongly indicated in those patients. Good antinociception may be even more important than it is assumed today. Anand demonstrated a lower morbidity and mortality in 45 newborns undergoing cardiothoracic surgery, when general anaesthesia was performed with high-dose sufentanil versus halothane supplementary doses of morphine. Anaesthesiologists have to reconsider the quality of general anaesthesia: the antinociception of their regimen.

Postoperative pain therapy in modern clinical practice still has significant deficits. Establishing acute pain services is reported to be a method of improving pain therapy. In this prospective study, 104 orthopaedic patients were treated with a postoperative epidural infusion of a combination of bupivacaine and sufentanil. Pain intensity and side effects were recorded daily by pain management personnel, and the pain therapy was adjusted according to the patients' need. The results showed that pain control was insufficient in 29 patients, and that side effects developed in 45 patients, included one patient with late respiratory depression. We conclude that acute pain service is essential in order to improve postoperative analgesia.

A review of the literature shows a constant need to improve the quality of postoperative pain management. The objective of this study was to decrease the intensity and variation of postoperative pain by developing a nurse-based pain service on the ward. An acute pain nurse was appointed and an educational programme with detailed algorithms was started. Regular pain intensity measurements were implemented. Postoperative pain intensity, treatments and side-effects were assessed both before and after the introduction of the new system in 400 patients divided into two consecutive groups of equal size. The number of patients with inadequately treated pain (actual pain > 3/10) dropped by 64% after major gynaecological surgery (25 vs 9%, 95% CI for differences 7-24%; p<0.001 for pain scores). On an average, inadequate pain relief (retrospective average pain > 3/10) on the first postoperative day was more frequent on the ward before than after the reform (47 vs. 21%; 95% CI for differences 15-35%; p<0.001 for pain scores). The incidence of side-effects was similar in both groups (p> 0.05). The intensity and variation of postoperative pain on the ward decreased by developing a nurse-based pain service with an acute pain nurse, an educational programme and regular pain intensity measurements.

The reduction in acute pain perception following dextromethorphan has previously been investigated in patients undergoing general anaesthesia. This random and double-blind study examined the effects of pre-incisional oral dextromethorphan on postoperative pain and intravenous patient-controlled morphine demand in 60 day-surgery patients undergoing lower body surgery under lidocaine (1.6%-16 ml) epidural anaesthesia after receiving placebo, 60 or 90 mg dextromethorphan, 90 min pre-operatively. Postoperative pain was scored on a visual analogue scale from 1 to 10. In-hospital observation continued for 6 h and for 3 days at home; diclofenac was available throughout. Dextromethorphan-treated patients reported significantly (p < 0.05) less pain and sedation, and felt better. Patients who received dextromethorphan 90 mg had significantly (p < 0.05) lower heart and respiratory rates than those who received 60 mg. Medicated patients required half the morphine and diclofenac of placebo patients: 38% of patients who received 90 mg and 21% who received dextromethorphan 60 mg used no morphine or diclofenac whatsoever, a previously unreported finding.
