Postoperative pain treatment for ambulatory surgery

One of the most significant changes in surgical practice during the last two decades has been the growth of ambulatory surgery. Adequate postoperative analgesia is a prerequisite for successful ambulatory surgery. Recent studies have shown that large numbers of patients suffer from moderate to severe pain during the first 24-48 hr. The success of fast-tracking depends to a considerable extent on effective postoperative pain management routines and the cost saving of outpatient surgery may be negated by unanticipated hospital admission for poorly treated pain. Depending on the intensity of postoperative pain current management includes the use of analgesics such as paracetamol, NSAIDs including coxibs and tramadol as single drugs or in combination as part of balanced (multimodal) analgesia. However, in the ambulatory setting many patients suffer from pain at home in spite of multimodal analgesic regimens. Sending patients home with perineural, incisional, and intra-articular catheters is a new and evolving area of postoperative pain management. Current evidence suggests that these techniques are effective, feasible and safe in the home environment if appropriate patient selection routines and organization for follow-up are in place.     

Postoperative epidural morphine is safe on surgical wards

The use of epidural morphine for postoperative analgesia outside of intensive care units remains controversial. In this report our anesthesiology-based acute pain service documents experience with 1,106 consecutive postoperative patients treated with epidural morphine on regular surgical wards. This experience involved 4,343 total patient days of care and 11,089 individual epidural morphine injections. On a 0-10 verbal analog scale, patient-reported median pain scores at rest and with coughing or ambulation were 1 (inter-quartile range 3) and 4 (interquartile range 4), respectively. The incidence of side effects requiring medication were as follows: pruritus 24%, nausea 29%, and respiratory depression 0.2%. There were no deaths, neurologic injuries, or infections associated with the technique. Migration of epidural catheters into the subarachnoid space and into epidural veins each occurred twice. Overall, 1,051 of the 1,106 patients (95%) experienced none of the following problems: catheter obstruction, premature dislodgement, painful injections, catheter migration, infection, or respiratory depression. We conclude that postoperative pain can be safely and effectively treated with epidural morphine on surgical wards.     

Postoperative pain

Treatment of postoperative pain has not received sufficient attention by the surgical profession. Recent developments concerned with acute pain physiology and improved techniques for postoperative pain relief should result in more satisfactory treatment of postoperative pain. Such pain relief may also modify various aspects of the surgical stress response, and nociceptive blockade by regional anesthetic techniques has been demonstrated to improve various parameters of postoperative outcome. It is therefore stressed that effective control of postoperative pain, combined with a high degree of surgical expertise and use of other perioperative therapeutic interventions including nutrition and mobilization, should be combined to improve overall perioperative care and surgical outcome.

Resumen El manejo del dolor postoperatorio no ha recibido suficiente atención por parte de la profesión quirúrgica. Los recientes desarrollos y avances relativos a la fisiología del dolor agudo y las técnicas avanzadas de control del dolor postoperatorio deben resultar un un manejo bastante más satisfactorio. Tal control del dolor puede también modificar diversos aspectos de la respuesta al etrés quirúrgico, así como el bloqueo que produce la anestesia regional ha demostrado mejorar varios parámetros del resultado postoperatorio. Se hace énfasis, por lo tanto, en que el eficaz control del dolor postoperatorio, en combinación con un alto grado de destreza quirúrgica y el uso de otras intervenciones terapéuticas perioperatorias, como el soporte nutricional y la movilización, deben ser empleados en conjunto para mejorar el cuidado general perioperatoro y el resultado quirúrgico final.

Résumé Le traitement de la douleur post-opératoire n'a pas été suffisement pris en compte jusquà présent par les équipes chirurgicales. Les recherches récentes dans le domaine de la physiologie des douleurs aigus et l'amélioration des techniques d'analgésie post-opératoire devraient permettre une meilleure prise en charge de la douleur post-opératoire. Une telle analgésie peut aussi modifier différents aspects de la réponse à l'aggression chirurgicale; ainsi il a été montré que le blocage des stimulations nociceptives par des techniques d'anésthésie régionale améliorait différents paramètres des suites post-opératoires. Il faut donc souligner qu'un contrôle effectif de la douleur post-opératoire, associé à une trés grande expérience chirurgicale et à l'utilisation d'autres moyens thérapeutiques péri-opératoires tels que le support nutritionel et le nursing devrait permettre d'améliorer l'évolution.

     

Postoperative treatment of phantom pain and causalgias with calcitonin

Results of IV calcitonin treatment in patients suffering from postoperative phantom limb pain (n = 12) or causalgia following peripheral nerve lesions (n = 4) are reported. All patients were complained of severe pain after a traumatic event or amputation, with disturbed sleep in many cases. After only 1-2 infusions 10 patients with phantom limb pain (83%) were discharged from hospital pain-free. Pain was effectively reduced by up to 5 infusions in 2 patients (17%). A follow-up for maximally 24 months showed a recurrence of pain in only 4 patients with obvious stump problems or reamputations. Three patients with causalgia also profited from a remarkable but transitory pain reduction; in 1 patient therapy was ineffective. Recurrent pain due to causalgia could not be improved by repeated calcitonin infusion, although this was effective for phantom limb pain. The administration of calcitonin IV can be recommended as a valuable treatment for phantom limb pain and causalgias in the early postoperative period. Therapy was effective with negligible side-effects, and long-term follow-up revealed a long-lasting effect.     

Postoperative pain experience: results from a national survey suggest postoperative pain continues to be undermanaged

Postoperative pain can have a significant effect on patient recovery. An understanding of patient attitudes and concerns about postoperative pain is important for identifying ways health care professionals can improve postoperative care. To assess patients' postoperative pain experience and the status of acute pain management, we conducted a national study by using telephone questionnaires. A random sample of 250 adults who had undergone surgical procedures recently in the United States was obtained from National Family Opinion. Patients were asked about the severity of postsurgical pain, treatment, satisfaction with pain medication, patient education, and perceptions about postoperative pain and pain medications. Approximately 80% of patients experienced acute pain after surgery. Of these patients, 86% had moderate, severe, or extreme pain, with more patients experiencing pain after discharge than before discharge. Experiencing postoperative pain was the most common concern (59%) of patients. Almost 25% of patients who received pain medications experienced adverse effects; however, almost 90% of them were satisfied with their pain medications. Approximately two thirds of patients reported that a health care professional talked with them about their pain. Despite an increased focus on pain management programs and the development of new standards for pain management, many patients continue to experience intense pain after surgery. Additional efforts are required to improve patients' postoperative pain experience. IMPLICATIONS: A survey of 250 US adults who had undergone a recent surgical procedure asked about their postoperative pain experience. Approximately 80% of patients experienced pain after surgery. Of these patients, 86% had moderate, severe, or extreme pain. Additional efforts are required to improve patients' postoperative pain experience.     

Postoperative pain management

Although scientific interest in the field of pain research is unremitting and the understanding of acute pain mechanisms has eminently advanced, it is evident that clinical practice of postoperative pain management still has major deficits. Indeed, the use of regional analgesia via a catheter, e.g. epidural analgesia (EDA), or patient controlled intravenous analgesia (PCIA) has become very popular. These methods require special equipment, adequate nursing skills and professional expertise as well as the establishment of clinical procedures and an appropriate logistic setup. However, the majority of patients are not managed by EDA or PCIA and cannot be ignored due to lack of knowledge of the proper use of basic analgesic treatment. Therefore, it makes sense to establish a standardized step-concept of postoperative pain management with regular quality control integrated into a multimodal perioperative rehabilitation program.     

Postoperative pain control

A survey of postoperative analgesia in 195 anaesthetic departments in England and Wales was undertaken. The results showed that 64% of respondents were dissatisfied or very dissatisfied with the present situation. Large differences were demonstrated between what was regarded as the safest technique and what would form the ideal management of postoperative pain.     

Postoperative pain guidelines

BACKGROUND AND OBJECTIVES: Postoperative pain is the expected but nonetheless undesirable byproduct of all surgical procedures. Humanitarian concerns and recent quasi-governmental regulations have heightened awareness about the importance of treating postoperative pain. This guideline builds upon the foundation created by the Agency for Health Care Policy and Research guideline published in 1993, highlights changes that have occurred over the past 10 years, and makes recommendations based on the current scientific evidence. In addition, it takes advantage of the versatile information management inherent in a web-based format to make the information readily available. METHODS: A multidisciplinary group of physicians, dentists, nurses, pharmacists, physical therapists, psychologists, and ethicists from the Veterans Health Administration (VHA) and Department of Defense (DoD) in conjunction with the VHA Office of Quality and Performance and a consultant group developed a postoperative pain algorithm and supporting documentation. The guideline structure and content were determined by a standardized rating of the evidence gleaned from comprehensive electronic searches. RESULTS: An interactive electronic and traditional "paper" guideline with a pre- and postoperative algorithm was developed. A table, which provides a menu of analgesic choices organized by specific operation, was constructed. Preferences for particular analgesic techniques and classes of medications were identified. A postoperative pain interactive pharmacopoeia and printable patient educational materials were also provided. The guideline may be reviewed at the following website: www.oqp.med.va.gov/cpg/cpg.htm. CONCLUSIONS: This postoperative pain guideline provides readily accessible information and evidence-based guidance to a variety of providers. It highlights deficiencies in our understanding of the pain and recovery processes and how they might guide our choices of postoperative analgesic techniques. In combination with the powerful system-wide data collection capabilities of the VHA, there may be improved understanding of what techniques are useful. Finally, it may lead to the development of reliable, individualized analgesic plans for specific surgical procedures that incorporate the full range of pharmacologic and nonpharmacologic techniques.     

Postoperative pain management

Postoperative pain can be effectively managed, even in the most complex oncologic procedures. Although the primary agents for treatment of severe pain continue to be opioids, routes of administration and dosing regimen have undergone a dramatic metamorphosis in the past 10 years. The intramuscular injection given every 4 hours has been replaced by patient-controlled analgesia and epidural techniques. Management of ancillary issues that contribute to an increased perception of pain (i.e., stress, depression, anxiety, and inflammation) must be included in an effective multimodal plan. Closer attention to the treatment of pain can obviate the consequences of poorly managed pain, which we are only beginning to understand. In this day of active consumerism in medicine, patients have come to expect improved pain management. Early outcome studies are beginning to confirm the belief that improved pain management translates into between outcomes and earlier dismissals. In the first century BC, Publilius Syrus, a Latin mime, wrote, "There are some remedies worse than the disease." For centuries, pain was inextricably linked to treatment. We may now be approaching a time in the development of medical care when this is no longer true.
