[Treatment of acute postoperative pain].

Postoperative pain is a subjective experience involving sensations and perceptions, which may be the result of tissue damage after surgery. Various analgesic drugs and techniques can be used to relief postoperative pain. They must be adapted to the surgery and to the patient. Moreover, adequate management of postoperative pain need to be organized. This include medical attitudes, clinical orientations, disciplinary involvements, consultative protocols and program education.

The role of COX-2 inhibitors in the treatment of postoperative pain.

Postoperative pain requires treatment not only to provide comfort to patients but also to improve postoperative outcome. Anti-inflammatory compounds are an important component of multimodal analgesia in the postoperative period. The newer cyclooxygenase (COX)-2 inhibitors are as effective as classical nonsteroidal anti-inflammatory drugs (NSAIDs) in this setting. However, COX-2 inhibitors offer a number of advantages over NSAIDs when used to treat postoperative pain. These include a reduced incidence of gastrointestinal ulceration and no inhibitory effect on platelet function and thereby a reduced risk of blood loss. Other benefits are less impairment of bone healing and no induction of bronchospasm in patients with aspirin-sensitive asthma. Increased cardiovascular thromboembolic events by COX-2 inhibitors have been reported after coronary artery bypass graft surgery only, but in general, surgery studies the incidence of such complications was comparable to placebo. Overall, COX-2 inhibitors offer a number of advantages over classical NSAIDs in the postoperative pain setting, but require the same caution with regard to renal effects.

A comparison of injection pain and postoperative pain of two intraosseous anesthetic techniques.

The purpose of this prospective, randomized, blinded study was to compare injection pain and postoperative pain of an apical primary X-Tip intraosseous technique to a coronal primary Stabident intraosseous technique in mandibular first molars. Using a repeated-measures design, 41 subjects randomly received 2 primary intraosseous injections at 2 separate appointments. Using a site distal to the mandibular first molar for both injections, the subjects received 1.8 mL of 2% lidocaine with 1: 100,000 epinephrine administered with the X-Tip system using an apical location in alveolar mucosa or 1.8 mL of 2% lidocaine with 1: 100,000 epinephrine administered with the Stabident system using a coronal location in attached gingiva. The pain of infiltration, perforation, needle insertion, solution deposition, mock or actual guide sleeve removal and postoperative pain were recorded on a Heft-Parker visual analogue scale (VAS) scale for the 2 intraosseous systems. The results demonstrated that the apical primary X-Tip intraosseous technique was not statistically different (P > .05) from the coronal primary Stabident technique regarding pain ratings of infiltration, perforation, needle insertion, solution deposition, mock or actual guide sleeve removal and postoperative pain (at the time subjective anesthesia wore off). However, on postoperative days 1 through 3, significantly (P < .05) more males experienced postoperative pain with the X-Tip system than with the Stabident system.

[The epideiology of postoperative pain].

Postoperative pain, as all types of pain, is a complex phenomenon including sensory, emotional and behavioural factors. The incidence and severity of postoperative pain is very variable between patients and is rather unpredictable. Patients characteristics as well as the types of surgery and anaesthesia will be of importance. Health professionals have a major role to play for improving effectiveness of pain management as well as safety.

[Epidural administration of midazolam with saline or bupivacaine for postoperative pain].

Postoperative pain relief and sedation with epidural midazolam-saline or midazolam-bupivacaine were studied in 46 patients after elective upper abdominal surgery. They were divided into 6 groups. In each group, 10 ml saline, 10 ml saline+midazolam 0.05 mg.kg-1, 10 ml saline+midazolam 0.1 mg.kg-1 (saline group), 0.25% bupivacaine 6 ml, 0.25% bupivacaine 6 ml + midazolam 0.05 mg.kg-1 or 0.25% bupivacaine 6 ml + midazolam 0.1 mg.kg-1 (bupivacaine group) was administered via epidural catheter for complaint of pain. For 120 minutes after epidural injection, blood pressure (BP), heart rate (HR), respiratory rate (RR), sedation score, and serum concentration of midazolam (conc midazolam) were evaluated. The time interval until next complaint of pain (pain relief time) was measured. In midazolam injected group, BP, HR, RR were not changed from preinjection value, but sufficient sedation was obtained and pain relief time was significantly prolonged compared with saline or bupivacaine injected group. Midazolam level was lower than that of sedation level. There were no significant differences between saline group and bupivacaine group, but the pain relief effect was slightly stronger in bupivacaine group. It is concluded that epidural saline - midazolam or 0.25% bupivacaine - midazolam is useful for postoperative pain relief after upper abdominal surgery.

Transcutaneous nerve stimulation for the treatment of postoperative pain.

Postoperative pain and rehabilitation parameters were compared in groups of patients with or without transcutaneous electric nerve stimulation (TENS) after orthopedic surgery. There was a subjective improvement, but only a non significant difference in opiate requirements with the use of TENS postoperatively; rehabilitation parameters turned out to be of limited value in evaluating its effect. Two patients had an allergic reaction after the use of TENS for postoperative pain relief.

[Does a means exist for prevention of postoperative pain?].

Postoperative pain can be prevented through pharmacological and non pharmacological means. The influence of the interval between therapy and surgical stimulus, which corresponds to "pre-emptive analgesia" in English-speaking countries (comparison of preoperative administration with pre- and postoperative administration of the same analgesic) has been assessed by numerous studies of good methodological quality. In spite of the initial promising results, most of the results published at present are negative. In an enlarged concept of postoperative pain prevention, various trials have demonstrated the benefits of the choice of the surgical approach, as well as the psychological preparation of the patient for surgery.

[Epidural midazolam for treatment of postoperative pain].

Postoperative pain relief and sedation with epidural midazolam were studied. Twenty-one patients for elective upper abdominal surgery were divided into 3 groups. Epidural catheter was inserted into thoracic epidural space before induction of general anesthesia. In each group, either 10 ml saline only, midazolam 0.05 mg.kg-1 + 10 ml saline, or midazolam 0.1 mg.kg-1 + 10 ml saline was injected into epidural catheter for complaint of pain in recovery room. For 120 minutes after epidural injection, blood pressure, heart rate, respiratory rate, serum concentration of midazolam, and sedation score were monitored. In midazolam injected groups, only slight changes were seen in blood pressure, heart rate, and respiratory rate. Sedation score was graded from 1 to 6:1 means complete sleep, and not responded to verbal command, 6 means agitated and many complaints. Midazolam 0.1 mg.kg-1 + 10 ml saline group had the lowest score, and saline 10 ml group had the highest score. Prolonged sedation and pain relief were obtained in midazolam injected group, especially 0.1 mg.kg-1 + 10 ml saline group. Serum midazolam concentrations were lower than 200 ng.ml-1. These values were considered as the lower limit for sedation by intravenous administration. In conclusion, epidural midazolam was useful for postoperative pain relief. The mechanism is considered to involve spinally mediated CNS action or direct spinal action.

Analgesics for orthopedic postoperative pain.

Postoperative pain management is critical for optimal care of orthopedic surgery patients. Opioids, administered intramuscularly, as epidurals, or IV as patient-controlled analgesia, are effective for severe pain. Adjunctive therapy and preemptive analgesia such as nerve blocks, and methods of delivery such as infusion pumps, may be used after total knee arthroplasty and anterior cruciate ligament (ACL) reconstruction. Oral opioids are effective for moderate to severe pain, and tramadol, with efficacy comparable to morphine but with fewer severe side effects, is selected for moderate to moderately severe pain. Opioid-sparing NSAIDs, such as ketorolac, and COX-2-specific NSAIDS have use in pain management of hip, knee, and ACL procedures. An individualized regimen of appropriate analgesics, combined with nonpharmacologic treatments such as physical therapy or cryotherapy and patient education, can aid orthopedic surgery patients' recovery.

Topical anesthesia with lidocaine aerosol in the control of postoperative pain.

Postoperative pain was assessed in patients undergoing inguinal hernia repair. Ten patients received lidocaine aerosol in the surgical wound before skin closure, ten patients received placebo aerosol devoid of lidocaine, and ten patients were untreated. The lidocaine-treated group had significantly lower pain scores and meperidine requirements during the first postoperative day compared to the control groups. During the second day after surgery, these variables did not differ between groups. Wound anesthesia, assessed by palpation of the wound 24 h after surgery by a blinded investigator, was significantly more pronounced in the group treated with lidocaine aerosol than in the control groups. Similarly, in patients undergoing bilateral herniorraphy, wound pain following palpation was significantly reduced on the lidocaine-treated side compared to the untreated side. Patients in the group receiving lidocaine aerosol indicated less pain in connection with mobilization than untreated patients, but not compared to patients treated with placebo aerosol. Plasma substance P (SP) and beta-endorphin (BE) measured in lidocaine-treated patients and in untreated patients before and after drug administration showed no significant differences regarding SP, while BE was significantly increased 1 h after surgery in the untreated group. Plasma lidocaine concentrations were well below toxic levels. Results show that lidocaine aerosol used as topical anesthetic in the surgical wound is simple to use, and results in a long-lasting reduction of pain after a single administration. Moreover, postoperative mobilization is facilitated, and the requirement for postoperative analgesics is reduced. Wound healing was normal, and no adverse reactions to lidocaine were reported.

Chronic back pain, acute postoperative pain and the activation of diffuse noxious inhibitory controls (DNIC).

The effect of the presence of either chronic or acute clinical pain on pain threshold and on the nociceptive flexion reflex (RIII) threshold was studied. The experimental pain sensation and the flexion reflex were evoked by trains of short electrical pulses. It was hypothesized that both kinds of clinical pain would be able to induce 'diffuse noxious inhibitory controls' (DNIC) and thereby raise the 2 experimental thresholds. Patients with chronic low back pain, patients with postoperative pain from oral surgery, and pain-free subjects were tested in 3 conditions: during baseline, after i.v. administration of a placebo, and after i.v. administration of naloxone. In comparison with 2 pain-free control groups, the 2 pain groups had a significantly higher pain threshold in all conditions. However, the RIII threshold was not significantly elevated in chronic or acute pain patients compared to controls. Naloxone had no effect on the RIII or pain threshold in any of the groups. It is concluded that the increased pain threshold which is frequently found in chronic pain patients, and which could be confirmed in the present study, does not result from a DNIC effect. The adaptation level theory offers an alternative explanation. Also, the acute postoperative pain in this study did not seem to induce DNIC. Because other forms of acute pain have been found to be effective in activating DNIC, future research should establish which pains are and which pains are not effective.

Preoperative morphine pre-empts postoperative pain.

Postoperative analgesia is usually inadequate, perhaps because conventional approaches to pain relief do not take account of underlying mechanisms. Pre-emptive analgesia may prevent nociceptive inputs generated during surgery from sensitising central neurons and, therefore, may reduce postoperative pain. In a randomised, double-blind study, we compared the effect of parenteral morphine when given before or after total abdominal hysterectomy in 60 patients. 10 mg of morphine were given intramuscularly 1 hour before operation (im pre), intravenously at induction of anaesthesia (iv pre), or intravenously at closure of the peritoneum (iv post). Response was assessed by morphine consumption from patient-controlled analgesia machines which was found to be significantly reduced in the iv pre group for 24 hours after operation compared with the iv post group. Pain sensitivity around the wound was reduced in both preoperative treatment groups compared with the iv post group. We conclude that pre-emptive analgesia with intravenous morphine, by preventing the establishment of central sensitisation during surgery, reduces postoperative pain, analgesic requirements, and secondary hyperalgesia.

Optimising postoperative pain management in the ambulatory patient.

Over 60% of surgery is now performed in an ambulatory setting. Despite improved analgesics and sophisticated drug delivery systems, surveys indicate that over 80% of patients experience moderate to severe pain postoperatively. Inadequate postoperative pain relief can prolong recovery, precipitate or increase the duration of hospital stay, increase healthcare costs, and reduce patient satisfaction. Effective postoperative pain management involves a multimodal approach and the use of various drugs with different mechanisms of action. Local anaesthetics are widely administered in the ambulatory setting using techniques such as local injection, field block, regional nerve block or neuraxial block. Continuous wound infusion pumps may have great potential in an ambulatory setting. Regional anaesthesia (involving anaesthetising regional areas of the body, including single extremities, multiple extremities, the torso, and the face or jaw) allows surgery to be performed in a specific location, usually an extremity, without the use of general anaesthesia, and potentially with little or no sedation. Opioids remain an important component of any analgesic regimen in treating moderate to severe acute postoperative pain. However, the incorporation of non-opioids, local anaesthetics and regional techniques will enhance current postoperative analgesic regimens. The development of new modalities of treatment, such as patient controlled analgesia, and newer drugs, such as cyclo-oxygenase-2 inhibitors, provide additional choices for the practitioner. While there are different routes of administration for analgesics (e.g. oral, parenteral, intramuscular, transmucosal, transdermal and sublingual), oral delivery of medications has remained the mainstay for postoperative pain control. The oral route is effective, the simplest to use and typically the least expensive. The intravenous route has the advantages of a rapid onset of action and easier titratibility, and so is recommended for the treatment of acute pain.Non-pharmacological methods for the management of postoperative pain include acupuncture, electromagnetic millimetre waves, hypnosis and the use of music during surgery. However, further research of these techniques is warranted to elucidate their effectiveness in this indication. Pain is a multifactorial experience, not just a sensation. Emotion, perception and past experience all affect an individual's response to noxious stimuli. Improved postoperative pain control through innovation and creativity may improve compliance, ease of delivery, reduce length of hospital stay and improve patient satisfaction. Patient education, early diagnosis of symptoms and aggressive treatment of pain using an integrative approach, combining pharmacotherapy as well as complementary technique, should serve us well in dealing with this complex problem.

[The effect of preoperative epidural morphine on postoperative pain].

Postoperative analgesia was assessed by examining nurses' records of 421 gynecological operative cases between January, 1989 and November, 1990. The criterion used in the analysis was the need for analgesics for pain within 24 hours postoperatively. After receiving morphine (2 mg, 4 mg, 5 mg, 6 mg) with local anesthetics or physiological saline solution into the epidural space (lower thoracic, lower lumbar, or both regions), the patient was intubated with thiopental, diazepam, and a muscle relaxant (vecuronium or pancuronium). Anesthesia was maintained with N2O, O2 and vecuronium or a pancuronium supplemented with a low concentration of enflurane or without enflurane. In the control group, anesthesia was maintained with an epidural block with local anesthetics and N2O, O2 supplemented with enflurane or without enflurane. In the groups receiving 2 mg or 4 mg of morphine, the percentage of patients with pain was 69.4+ (34 out of 49 cases) and 54.5% (30 out of 55 cases), respectively. Also, in the groups receiving 5 mg or 6 mg of morphine, the percentage of patients with pain was 39.5% (15 out of 38 cases) and 22.4% (51 out of 224 cases), respectively. In the control group, (with no epidural morphine) 89.1% (49 out of 55 cases) required analgesics. The percentage of patients without pain was significantly larger in the group receiving 6 mg of morphine even in comparison with the groups receiving lesser doses. No serious complications occurred postoperatively in any group. In conclusion, preoperative morphine administered into the epidural space is effective for postoperative analgesia in gynecological operation, especially when morphine 6 mg was administered in the lower epidural (4 mg) and lower lumbar epidural (2 mg) space.

[Quality of the postoperative course and patients' satisfaction produced by a system of postoperative pain control: postoperative clinical evidence that influences the quality of the postoperative course].

UNLABELLED: Acute pain treatment after surgery or trauma, when inadequate, contributes to increased morbidity and prolonged in hospital stay. Acute postoperative pain management can be realised by application of treatment protocols and the regular assessment of the patients clinical conditions. The aim of the ACUTE PAIN SERVICE (APS) is to plan postoperative treatment. According to our experience, besides providing assistance, the APS elaborates results and intervenes through regular audits to improve quality. This system is further enriched through collection of information obtained through an anonymous questionnaire compiled by the patients about forty eight hours after surgery. The questions are expressed such to outline a judgement about patients' satisfaction towards the services supplied by the agency. OBJECTIVE: Evaluation of effectiveness of pain treatment and level of postoperative wellbeing through continuous observation of the patient. METHODS: a retrospective study on about 4400 consecutive patients arriving at the APS in the last 2 years of activity, who have been evaluated at fixed moments using various indicators (VAS at rest/activity, PONV and other discomforts). RESULTS: Follow-up of the patients showed that: - pain relief, when reached, does not conform well-being; - for certain symptoms of discomfort, specific protocols are necessary; - there are correlations between type of surgery, type of anaesthesia and discomfort, which may be reducible through the right attitude in behaviour and therapy; - antalgic therapy itself can cause several side-effects. The solution of the discomfort problem gets close to the concept of perioperative medicine in which APS action goes beyond pain, towards a more complete pain management.
