Quality of life (QOL) after video-assisted thoracic surgical (VATS) lobectomy remains to be defined. Forty-four consecutive patients with clinical stage I lung cancer underwent lobectomy by the VATS approach (n = 22 patients) or thoracotomy approach (n = 22 patients). Acute pain was quantitated by postoperative narcotic requirements and the need for epidural anesthesia. Long-term QOL was assessed by questioning patients about the presence of chronic chest pain, ongoing limitations in arm or shoulder function, time until return to preoperative activity, and satisfaction with the operation. Patients who underwent VATS lobectomy had significant decreases in both acute and chronic chest pain and time until return to preoperative activity. Patients also had more confidence regarding wound size and their overall impression of the operation. In this series, VATS lobectomy was associated with long-term benefits for the QOL in patients with lung cancer. However, the exact role of this approach should be defined by carefully-designed controlled trials studying long-term survival.

First, the fundamentals of impulse transmission and pain perception are revised. The role of the primary afferent nociceptors is explained. Dental pain is described as a form of acute pain and the mechanism of nociception is fundamental. Peripheral and central sensitization can evolve. The second part covers the pharmacological aspects. Local anesthetics reduce impulse transmission by interfering with the mechanism of normal depolarisation. Binding to specific receptors located at the nerve membrane, more specifically on the sodium channel, results in decreased or eliminated permeability to sodium ions and leads to interruption of nerve conduction. The different types of local anesthetics used in dentistry are discussed in more detail with respect to their physico-chemical characteristics and analgetic properties. The importance of factors such as lipophilicity, degree of protein binding and dissociation constant pKa are explained together with the clinical implications of pH and possible toxic effects. Failure of local anesthesia can be the result of problems with the administration of the product or can have a pharmacological basis. Injection of the anesthetic should take place in amounts large enough, with suitable volume and as close as possible to the nerve. When infection and inflammation are present, the intravascular resorption of the anesthetic will accelerate and the lowered pH influences diffusion negatively. Repetitive administration can induce the phenomenon of tachyfylaxis (decreased anesthetic effect).

The Health Services, not only the Italian one, is under pressure because of request for improving treatment quality and the financial need for reorganization and cost-saving. It's required a rationalization of intervention, together with a careful choice of the best and cheapest techniques and the demonstration of their efficacy. The anaesthesia service activity, in a period of cost rationalization and funds restriction should be aimed to appropriate outcome measures corrected by both patient's risk factors and surgical-anaesthesiological case-mix. The development of a complete strategy for surgical pain management might run into two phases. The first phase, internal and mono-specialistic, should develop like the creation of an Acute Pain Team. The main processes are: focusing the problem (charge of the care), training, information, teaching methodology (timing, methods, drugs, techniques, etc.) and the audit (before and after changes). The main aims are the evaluation of the level of analgesia and pain relief or patient's satisfaction which are partial endpoints useful to demonstrate the improvement and the efficacy of the new pain management strategies. The second phase, multidisciplinary, is directed toward the creation of a Postoperative Evaluation Team. The main objective is to set up a collaborative clinical group able to identify the criteria for quality, efficacy and safety. The major purpose is the evaluation of major outcome measures: surgical outcome, morbidity, mortality and length of hospitalization. The improvement in the quality of postoperative pain treatment goes through a better organization and a progressive increase of the already available therapy. The achievement of the result and the quality projects depend on the interaction among staff members with different behaviours and settings. Internal teaching and training, continuous education for doctors and nurses, and external information, marketing and improvement of attractive capability of Institution, are the procedures of a growing integrated program for postoperative pain treatment. The organizational processes should interact effectively with a plan of education, updating, revision and information in a definite development timing. It should be emphasized a collaborative, interdisciplinary approach to pain control, assessment and treatment, including all the members of the health care team, with an input from the patient and a protective collaboration from the Institution. The development of a postoperative care team must be considered as part of the largest project for "a Painfree Hospital". It represents a keystone of a Institutional Quality Assurance Plan for health care providers, patients (customs) and Institution.

The trial aimed at development of pathogenetically sound complex of therapeutic measures to prevent postoperative pain or relieve it significantly included 1912 patients after elective surgical interventions on the lower part of the body. It is shown that basic factors in postoperative pain prevention are the following: a) adequate relief of preoperative pain syndrome; b) use of spinal or spinal-epidural anesthesia as the leading anesthesia method; c) preoperative epidural administration of opioid analgetic drugs; d) pre-, intra- and postoperative administrations of drugs affecting N-methyl-D-aspartate-receptors (ketamine, magnesium sulphate) as well as inhibitors of kininogenesis and prostaglandinogenesis. The success lies in a multimodality approach to prevention of postoperative pain syndrome, i.e. maximal eradication of all the factors promoting onset of pain during pre-, intra- and postoperative period with a simultaneous impact on peripheral and central mechanisms of acute pain. Such an approach resulted in a complete prevention of postoperative pain in 46.2% patients while the rest patients had much less intensive pain.

Perioperative medicine starts with preoperative assessment and preparation of patients undergoing various procedures. It includes intraoperative care and continues postproceudral management, from recovery room to intensive care and step-down facilities. Acute pain management must be optimized in order to enhance rehabilitation and restoration of functions. Perioperative medicine also includes management of acute and chronic pain. Potential areas of anesthesia involvement, still unclear, include preoperative and postoperative ward management and complete preparation such as cardiology or pulmonary testing. Further steps to take in the direction of perioperative medicine are the development of a different model of resident training, and the improvement of information technology and medical record.

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.

The constant search for increased efficiency and reduction of hospital length of stay has led to an increase number of major orthopedic procedures performed as outpatients and the increase in the associated intensity and duration of acute postoperative pain. Although, it is well established that single peripheral blocks provide adequate anesthesia and excellent immediate postoperative analgesia in patients undergoing minor ambulatory orthopedic surgery, the postoperative acute pain benefit is limited to less than 24 hours. However, many patients required over 24 hours of intensive postoperative analgesia. Furthermore the need for immediate postoperative physical therapy in orthopedics dictates that local anesthetics be chosen on the basis of their safety and ability to produce preferential sensory blocks. As early as 1946, Ansbro proposed the use of continuous nerve blocks to prolong the duration of analgesia of nerve block technique during anesthesia. Continuous nerve blocks have also been used for the acute postoperative pain control of patients undergoing major orthopedic surgery as in-patients. This technique has been proven to be safe and effective in controlling acute postoperative pain and improve functional outcome. The recent introduction of safer local anesthetics producing preferential sensory blocks along with the development of ambulatory pumps has allow to extend the use of these continuous block techniques to ambulatory patients. Recent development also included the use of cox2 inhibitors along with cold maximize postoperative analgesia. This multimodal approach has been proven to be safe and efficacious as much for resting pain than pain associated with exercise.

Effective and safe pain management for a patient emerging from the effects of anesthesia is a specialized skill that is often acquired only through years of experience. This article provides perianesthesia nurses with a technique to assess the cognitively impaired postanesthesia patient and to incorporate vital circumstantial criteria in determining the presence of pain. Intervention recommendations are also included. The pain management algorithm includes research-based information from the following sources: Pain: Clinical Manual (ed 2), by pain nurse experts Margo McCaffery, RN, MS, FAAN, and Chris Pasero, RN, MS; and the American Pain Society's Principles of Analgesic Use in the Treatment of Acute Pain and Cancer Pain (ed 4). Parameters are incorporated for clinical use.

To describe facilities for postoperative epidurals in UK National Health Service Hospitals, a questionnaire was sent to each hospital performing surgery below the head and neck. Of 271 hospitals, 256 replied (95%). While almost all offer postoperative epidurals, only 78 (30%) offer them to all surgical disciplines. Most hospitals rely on acute pain nurses for troubleshooting during the day, and on trainee anaesthetists after hours. Administration is most commonly by continuous infusion. There was no restriction on the use of epidural opioids in 67% of hospitals. Most (96%) hospitals have a protocol for epidural care, although the specified level of monitoring varies widely. There is no consensus of practice on removal of epidural catheters relative to anticoagulation. Levels of training in epidural care also vary widely. Two hundred and thirty-six hospitals (92%) have an acute pain team. Despite the expansion in acute pain services, facilities for postoperative epidurals are deficient in many NHS hospitals.

Acupuncture has been shown to be effective in experimental and clinical acute pain settings. This study aims to evaluate the effect of preoperative electroacupuncture (EA) on intraoperative and postoperative analgesic (alfentanil and morphine) requirement in patients scheduled for gynaecologic lower abdominal surgery. Ninety patients were randomly assigned to one of three groups: Group I (control group)--received placebo EA for 45 minutes before induction of general anaesthesia (GA); Group II--preoperative EA instituted 45 minutes before induction of GA; Group III--45 minutes of postoperative EA. The Bispectral Index monitor was used intraoperatively to monitor the hypnotic effect of anaesthetic drugs, and alfentanil was titrated to maintain the blood pressure and pulse rate within +/- 15% of basal values. Postoperative pain was managed by intravenous morphine via a patient-controlled analgesia (PCA) device. Patients in Group II (0.44 +/- .15microg/kg/min) received less alfentanil than those in Group III (0.58 +/- .22 microg/kg/min) (p = p.024), but not significantly less than those in Group I 10.51 +/- 0.21 microg/kg/min) (p = 0.472). Postoperative morphine consumption was numerically lower in Group II compared with the other groups; however, the difference was statistically significant only during the period of 6-12 hours between Group II [0.03 (0.05) mg/kg] and Group I [0.10 (0.11) mg/kg] (p = 0.015), and Group II and Group III [0.08 (0.10) mg/kg] (p = 0.010). The 24-hour cumulative morphine consumption for Group II (0.52 +/- .19mg/kg) was less than that for either Group I I0.68 +/- 38mg/kg) or Group III (0.58 +/- .27mg/kg), but the difference did not reach significance. In conclusion, preoperative EA leads to a reduced intraoperative alfentanil consumption, though this effect may not be specific, and has a morphine sparing effect during the early postoperative period.
