We sought in this prospective study to use a multimodal approach to reduce stress and improve recovery in patients undergoing major surgery. During an initial study period, 30 patients were randomly allocated to receive general anesthesia (GA; Group 1) or a combination of GA and intraoperative thoracic epidural analgesia (TEA; Group 2) when undergoing radical cystectomy. Parenteral nutrition was provided for 5 days after surgery. During the second period, 15 patients were treated with a multimodal approach (Group 3) consisting of intraoperative GA and TEA, postoperative patient-controlled TEA, early oral nutrition, and enforced mobilization. Data for plasma and urine catecholamines, plasma cortisol, the nitrogen balance, the postoperative inflammatory nutrition index, pain relief, fatigue, sleep, overnight recovery, recovery of bowel function, and mobilization were recorded up to the fifth postoperative day. Plasma concentrations of catecholamines and cortisol were comparable in all patients, but those in Group 3 had lower levels of urinary catecholamine excretion. Protein intake was more effective with parenteral nutrition. Nitrogen balances were less negative, and the postoperative inflammatory nutrition index score increased significantly in the traditional groups but not in Group 3. Multimodally treated patients reported less fatigue and better overnight recovery. Along with improved pain relief, recovery of bowel function, and ambulation, there were no differences in the postoperative complication rates among the three groups. The multimodal approach reduced stress and improved metabolism and recovery after radical cystectomy.

Randomized phase III studies reported this year prove that docetaxel is superior both to best supportive care (BSC) and to a standard regimen of vinorelbine or ifosfamide as second-line therapy for advanced non--small cell lung cancer. In a landmark study authored by Dr Frances Shepherd, 204 patients with stage IIIB/IV non--small cell lung cancer who had failed previous cisplatin-based chemotherapy were randomized to receive either docetaxel (100 mg/m(2) or 75 mg/m(2) every 3 weeks) or BSC. The median survival of patients assigned to docetaxel was 7.6 months, significantly longer than the median of 4.6 months in patients treated with BSC alone. The rate of febrile neutropenia was 22% in patients receiving 100 mg/m(2) docetaxel but only 1.8% when the dose was 75 mg/m(2). Patients treated with docetaxel required less additional opioid analgesia and palliative radiotherapy than those receiving BSC. Patients in the docetaxel 75 mg/m(2) arm also were significantly less likely to lose 10% or more body weight and to experience severe fatigue. In a second phase III study led by Dr Frank Fossella, 373 patients were randomized to docetaxel 100 mg/m(2), docetaxel 75 mg/m(2), or a control arm of vinorelbine 30 mg/m(2) or ifosfamide 2 g/m(2). Median survival was similar between the two groups (range, 5.5 to 5.7 months). However, the survival rate at I year was significantly higher in patients assigned to 75 mg/m(2) than in the control arm. Patients receiving docetaxel 75 mg/m(2) experienced better global quality of life (Lung Cancer Symptom Scale: patient-rated) than patients receiving vinorelbine or ifosfamide. A higher incidence of grade 4 neutropenia and febrile neutropenia was observed in the docetaxel arms of the study, but the incidence of infections was low and nonhematologic toxicities were similar across all treatment arms. These studies show docetaxel provides meaningful survival and clinical benefits in second-line non-small cell lung cancer. The dose recommended in this setting is 75 mg/m(2) every 3 weeks.

Children frequently received no treatment, or inadequate treatment, for pain and for painful procedures. The newborn and critically ill children are especially vulnerable to no treatment or under-treatment. Nerve pathways essential for the transmission and perception of pain are present and functioning by 24 weeks of gestation. The failure to provide analgesia for pain results in rewiring the nerve pathways responsible for pain transmission in the dorsal horn of the spinal cord and results in increased pain perception for future painful results. Many children would withdraw or deny their pain in an attempt to avoid yet another terrifying and painful experiences, such as the intramuscular injections. Societal fears of opioid addiction and lack of advocacy are also causal factors in the under-treatment of pediatric pain. False beliefs about addictions and proper use of acetaminophen and other analgesics resulted in the failure to provide analgesia to children. All children even the newborn and critically ill require analgesia for pain and painful procedures. Unbelieved pain interferes with sleep, leads to fatigue and a sense of helplessness, and may result in increased morbidity or mortality.

The stress system coordinates the adaptive responses of the organism to stressors of any kind.(1). The main components of the stress system are the corticotropin-releasing hormone (CRH) and locus ceruleus-norepinephrine (LC/NE)-autonomic systems and their peripheral effectors, the pituitary-adrenal axis, and the limbs of the autonomic system. Activation of the stress system leads to behavioral and peripheral changes that improve the ability of the organism to adjust homeostasis and increase its chances for survival. The CRH and LC/NE systems stimulate arousal and attention, as well as the mesocorticolimbic dopaminergic system, which is involved in anticipatory and reward phenomena, and the hypothalamic beta-endorphin system, which suppresses pain sensation and, hence, increases analgesia. CRH inhibits appetite and activates thermogenesis via the catecholaminergic system. Also, reciprocal interactions exist between the amygdala and the hippocampus and the stress system, which stimulates these elements and is regulated by them. CRH plays an important role in inhibiting GnRH secretion during stress, while, via somatostatin, it also inhibits GH, TRH and TSH secretion, suppressing, thus, the reproductive, growth and thyroid functions. Interestingly, all three of these functions receive and depend on positive catecholaminergic input. The end-hormones of the hypothalamic-pituitary-adrenal (HPA) axis, glucocorticoids, on the other hand, have multiple roles. They simultaneously inhibit the CRH, LC/NE and beta-endorphin systems and stimulate the mesocorticolimbic dopaminergic system and the CRH peptidergic central nucleus of the amygdala. In addition, they directly inhibit pituitary gonadotropin, GH and TSH secretion, render the target tissues of sex steroids and growth factors resistant to these substances and suppress the 5' deiodinase, which converts the relatively inactive tetraiodothyronine (T(4)) to triiodothyronine (T(3)), contributing further to the suppression of reproductive, growth and thyroid functions. They also have direct as well as insulin-mediated effects on adipose tissue, ultimately promoting visceral adiposity, insulin resistance, dyslipidemia and hypertension (metabolic syndrome X) and direct effects on the bone, causing "low turnover" osteoporosis. Central CRH, via glucocorticoids and catecholamines, inhibits the inflammatory reaction, while directly secreted by peripheral nerves CRH stimulates local inflammation (immune CRH). CRH antagonists may be useful in human pathologic states, such as melancholic depression and chronic anxiety, associated with chronic hyperactivity of the stress system, along with predictable behavioral, neuroendocrine, metabolic and immune changes, based on the interrelations outlined above. Conversely, potentiators of CRH secretion/action may be useful to treat atypical depression, postpartum depression and the fibromyalgia/chronic fatigue syndromes, all characterized by low HPA axis and LC/NE activity, fatigue, depressive symptomatology, hyperalgesia and increased immune/inflammatory responses to stimuli.

The orthopaedic surgeon brings to the operating room some of the greatest challenges for the anaesthesiologist. Various factors, such as age, health status, disease process, type and extent of operative procedure, provide differing circumstances, which an anaesthesiologist is obliged to cope with. This contrasts to other surgical specialities in which patient factors and operative procedures are much more predictable. The number of older patients in orthopaedics is steadily growing, and the anaesthesiologist has to take all measures to permit an early and efficient rehabilitation, a concept which is now widely recognized for improving the success of orthopaedic surgical procedures. Factors which may hinder this concept are post-operative pain, central nervous system dysfunction, fatigue, deep sedation, delayed enteral feeding and absorption. There is no evidence that regional anaesthesia without the use of the continuous regional analgesic technique decreases morbidity and mortality as compared to general anaesthesia, in this context. However, the advantages of continuous analgesia through a perineural spinal or epidural catheter are promising and deserve further investigation. The concept of the optimal post-operative multimodal regimen needs to be defined. The application of NSAID and paracetamol is an integral part of this concept, and the dose of opioids should be titrated to the lowest efficient dose needed. Thus, this chapter discusses the different controversies and future trends of anaesthesia with regard to the elderly in orthopaedic surgery.

Misuse of opioids is associated with abnormalities of pituitary function. Patients with chronic pain frequently complain of fatigue and undergo endocrine testing. To test whether oral opioid treatment causes abnormal pituitary function we prospectively assessed pituitary function in 37 patients with chronic pain who were receiving either oral opioid analgesia or non-opioid analgesia. Oral opioid treatment was not associated with abnormal pituitary function although a few patients had abnormal results mainly related to obesity. Our results suggest that patients with chronic pain who have abnormal endocrine results should have a complete assessment, since abnormal test results cannot be attributed to their analgesia.

Surgical injury can be followed by pain, nausea, vomiting and ileus, stress-induced catabolism, impaired pulmonary function, increased cardiac demands, and risk of thromboembolism. These problems can lead to complications, need for treatment in hospital, postoperative fatigue, and delayed convalescence. Development of safe and short-acting anaesthetics, improved pain relief by early intervention with multimodal analgesia, and stress reduction by regional anaesthetic techniques, beta-blockade, or glucocorticoids have provided important possibilities for enhanced recovery. When these techniques are combined with a change in perioperative care a pronounced enhancement of recovery and decrease in hospital stay can be achieved, even in major operations. The anaesthetist has an important role in facilitating early postoperative recovery by provision of minimally-invasive anaesthesia and pain relief, and by collaborating with surgeons, surgical nurses, and physiotherapists to reduce risk and pain.

Adverse and analgesic effects of acupuncture during the second and third trimesters of pregnancy were studied retrospectively in an observational study including 167 consecutive patients with lower back pain, pelvic pain, or both. In each patient acupuncture was given on at least two different occasions by three manual stimulations of two or more acupuncture or tender points, mainly LR-3 and LI-4 together with local tender points, at 15-min intervals. Possible adverse and analgesic effects were assessed by the midwife responsible for the acupuncture given in each patient. There were no abortions and no influence on the delivery course of the infants, but transient premature labor was observed during the fourth stimulation carried out in the 15th gestational week in one woman. Other possible adverse effects, like transient dizziness or tiredness, were reported in 35 patients (21%). Analgesia, as assessed by midwives involved, was good or excellent in 72% of patients. Acupuncture seems to be safe and effective for pain relief in lower back pain, pelvic pain, or both during the second and third trimesters of pregnancy. Nevertheless, prospective randomized studies are needed to confirm these findings.

Isolated fractures of the first rib are uncommon. They are caused by major blunt trauma, a violent muscular pull, or fatigue. Diagnosis is usually made by chest radiography and computed tomography. Angiography is justified when certain criteria are met. Treatment is rest and mild analgesia. Early and late complications have been reported and are treated accordingly. The purpose of this article is to report a case of first rib stress fracture in a kick boxer and review the pertinent literature.

Multi-modal rehabilitation with an emphasis on preoperative information, reduction of surgical stress responses, optimized dynamic pain relief with continuous epidural analgesia and early mobilization and oral nutrition may reduce hospital stay, morbidity, convalescence, and costs (fast-track surgery). Current results from fast-track colonic surgery suggest that postoperative pulmonary, cardiovascular, and muscle function are improved and body composition preserved as well as a normal oral intake of energy and protein can be achieved. Consequently, hospital stay is reduced to about 2-4 days, with decreased fatigue and need for sleep in the convalescence period. Despite a higher risk for readmissions, overall costs and morbidity seem to be reduced. Existing data from several institutions support the concept of fast-track colonic surgery to improve postoperative organ functions, thereby allowing for early rehabilitation with decreased hospital stay, convalescence, and costs. Further data are needed from multi-national institutions on morbidity, safety, and costs.
