Postoperative pain after surgery in the cerebellopontine angle (CPA) is acknowledged to occur, but is rarely taken into account as a factor in the analysis of morbidity of such surgery. It is widely acknowledged that some patients, having undergone such surgery, particularly by means of the suboccipital approach, report significant post-operative pain and headache. This study was undertaken to determine the incidence and severity of pain after excision of acoustic neuromas and to establish whether this differed between the suboccipital and translabyrinthine routes. Ninety-one percent of all patients (n = 58), who had the suboccipital approach used for removal of their tumor, were surveyed. A smaller group (n = 40), matched for tumor size, age, and sex, but in whom the translabyrinthine approach was used, was similarly studied. A standard questionnaire, designed to detect and quantify postoperative pain, was administered to each patient. Of patients who underwent tumor excision by means of the suboccipital approach, 63.7% experienced significant local discomfort and headache, whereas this was notably absent in all those who had undergone translabyrinthine excision. In view of the significant morbidity noted to follow the suboccipital approach, several modifications of the surgical technique used were devised.

One hundred patients (aged 22-86 years, mean 62.5), undergoing lower limb orthopaedic surgery, received continuous spinal anaesthesia using a 28 s.w.g. catheter inserted through a 22 s.w.g. Quincke needle. Post-operative pain relief was provided by bolus injections of 1-2.5 mL 4 h-1 of plain 0.25% bupivacaine. The mean dose of bupivacaine required for sufficient pain relief in 93% of patients was 1.6 +/- 0.2 (1.3-1.9) mL 4 h-1. The highest dose was needed between 4 and 8 h post-operatively. No dependence of dose on age or type of operation was found. Technical problems with the microcatheter occurred in 12%. The most frequent complaint was post-operative backache (12%). Only one patient suffered from post-dural puncture headache on the day after surgery. There was no microbiological contamination of the catheter tips after removal. In the post-operative interview, 89% of the patients were completely satisfied with CSA; 91% would prefer this technique to general anaesthesia.

Recently, it has become obvious that disabling postoperative headache is a major problem with acoustic neuroma surgery. A questionnaire was used to retrospectively evaluate the incidence, clinical features, prognosis and possible therapeutic measures of this particular form of headache. Forty-two percent (42%) of patients had some headache prior to surgery but this was not a major complaint. After surgery, 75% of patients experienced headache. Only 24% had complete relief of headache. A very gradual improvement of the pain occurred in 32%. Pathogenesis remains unclear, but clinical characteristics of the headache suggest a combination of tension-type, neuralgic and vascular components. Postoperative pain occurs mostly around the surgical site suggesting that this type of headache is the result of surgical trauma. A prospective long-term study is needed to delineate this condition further. Some therapeutic suggestions are offered.

Postoperative pain relief and sedation with epidural ketamine were studied. Twenty-four patients for elective upper abdominal surgery were divided into 4 groups. Epidural catheter was inserted into thoracic epidural space before induction of general anesthesia. In each group, either 0.25% bupivacaine 5 ml only, ketamine 0.1 mg.kg-1 + bupivacaine 5 ml, or ketamine 0.3 mg.kg-1 + bupivacaine 5 ml, or ketamine 0.5 mg.kg-1 + bupivacaine 5 ml was injected into epidural catheter for complaint of pain in recovery room. In ketamine injected groups, blood pressure and heart were unchanged, but respiration rate increased significantly. Patients in ketamine 0.3 or 0.5 mg.kg-1 injected groups, pain relief and sedation score were significantly intensified, but patients in ketamine 0.5 mg.kg-1 injected group, incidence of pain in the back during injection and headache was high. We conclude that epidural ketamine is useful for postoperative pain relief, and the superior dose of epidural ketamine is 0.3 mg.kg-1.

The alpha-adrenergic agonists have been demonstrated to have synergistic effects with opioids and local anesthetics in animal research. The present study was performed to determine whether the addition of adrenaline improves the analgesic effects of an epidural infusion of a combination of fentanyl and bupivacaine after abdominal surgery. We studied 90 ASA 1 or 2 patients scheduled for abdominal surgery under epidural anaesthesia, with or without general anaesthesia. Patients were randomly divided into two groups to receive a postoperative epidural infusion of fentanyl 5 micrograms/ml in bupivacaine 0.2%, with or without adrenaline 5 micrograms/ml, at a rate of 2 ml/h for more than 48 hours. Postoperative pain relief was assessed using visual analog scales (VAS), both at rest and during coughing, at 2, 24, and 48 hours after surgery. The number of rescue analgesics and side-effects such as nausea, vomiting, pruritus, respiratory depression, headache, muscle weakness, and hypotension were recorded. Patients who received adrenaline (n = 40) reported significantly lower mean VAS scores than those who received no adrenaline (n = 37), both at rest at 24 hours postoperatively and during coughing at 24 and 48 hours. The number of additional analgesics and incidence of side-effects did not differ between groups. In conclusion, the results of the present study demonstrate that the addition of adrenaline to a combination of fentanyl and bupivacaine improves the quality of epidural analgesia after abdominal surgery. Under the conditions of the study, we did not detect any disadvantage from the addition of adrenaline.

The clinical effect of bipolar radiofrequency thermotherapy on allergic rhinitis was evaluated. A bipolar radiofrequency system (CelonLab ENT) was used to treat 16 patients suffering from allergic rhinitis between February 2003 and August 2003. The thermotherapy was performed under local anesthesia at the otolaryngology outpatient clinic of St. Marianna University Toyoko Hospital. Data were collected by questionnaire and rhinomanometry preoperatively and 2 months postoperatively. The mean visual analogue scale (VAS) score for intraoperative pain was 31 mm (range, 0-100), and nearly all the patients felt no or a subtle pain during the thermotherapy. Postoperative pain was also well tolerated, with nearly all the patients not requiring analgesic drugs. Postoperative bleeding was minor, and none of the patients required additional treatment for bleeding. Nearly all the patients reported an improvement in their nasal patency, rhinorrhea, headaches, and sleeping. Statistically significant improvements were observed for all the measured VAS scores: nasal patency, rhinorrhea, headache, and olfactory function. Nasal resistance, as measured by anterior rhinomanometry, significantly improved after treatment. The effect of decongestion was also measured using anterior rhinomanometry. The ratio of nasal resistance before and after decongestion was significantly higher after thermotherapy, suggesting that nasal decongestion had a smaller effect on nasal patency after treatment. The current results suggest that the CelonLab ENT device is an effective and safe treatment for allergic rhinitis.

The aim of the study was to evaluate whether topical application of 0.2% glyceryl trinitrate ointment could reduce post-haemorrhoidectomy healing time and pain both at rest and during defecation. Thirty patients with grade III and IV haemorrhoids were included in the study and divided into two groups. All patients underwent Milligan-Morgan haemorrhoidectomy, and anorectal manometry was performed before surgery and after 5 and 30 days. In one group a placebo ointment was applied to the perianal wounds, while in the other group a 0.2% glyceryl trinitrate ointment was used. Maximum resting pressure was reduced in the glyceryl trinitrate group and increased in the placebo group after 5 days. Postoperative pain both at rest and during defecation, and the time to healing and return to normal activity were significantly reduced in the glyceryl trinitrate group, whilst analgesic consumption was similar. An elevated incidence of headache was observed In the glyceryl trinitrate group. Topical application of glyceryl trinitrate was effective in reducing postoperative pain and healing time, but the substantial incidence of side effects may limit its extensive use.

Extended spinal anaesthesia using a spinal micro-catheter was used as a primary method of anaesthesia for elective colorectal cancer surgery in 68 high risk patients over a 14-year period in our institution. The technique was also useful in eight elective and 13 emergency abdominal surgeries. All patients suffered from severe chronic obstructive airway disease requiring multiple inhalers and drugs (ASA III). Thirty nine of these patients also suffered from angina, myocardial infarction, diabetes and other systemic diseases (ASA IV). Surgery included right hemicolectomy, left hemicolectomy, total colectomy, sigmoid colectomy, Hartman's resection, anterior resection of rectum, abdominoperineal resection, cholecystectomy (open and laparoscopic) and obstructed inguinal hernia requiring laparotomy. Spinal anaesthesia was performed under strict aseptic conditions with a 22 gauge spinal needle with a mixture consisting of 2.75ml of 0.5% heavy bupivacaine and 0.25ml of fentanyl (25microg). This was followed by placement of a spinal micro-catheter and the duration of anaesthesia was extended by intermittent injection of 0.5% isobaric bupivacaine. Brief hypotension occurred in 12.4% of patients during the establishment of anaesthetic block height to T6-7 and was duly treated with intravenous administration of fluid and ephedrine hydrochloride. Good anaesthesia resulted in all patients except for brief discomfort in some patients during hemicolectomy surgery possibly due to the dissection and traction on the peritoneum causing irritation to the diaphragm. The use of sedation was avoided. General anaesthesia was administered in one patient and this patient required postoperative ventilation and cardiovascular support in the Intensive Care Unit. The spinal micro-catheter was removed at the end of surgery. Postoperative pain relief was obtained by administering intravenous morphine through a patient controlled analgesia machine in the critical care ward area (High Dependency Unit). There was a low incidence of minor postoperative side effects such as nausea (14.6%), vomiting (7.9%), minor post dural puncture headache (5.6%) and pruritus (5.6%). We conclude that spinal anaesthesia with a micro-catheter may be used as a primary method of anaesthesia for colorectal cancer surgery and other major abdominal surgery in high-risk patients for whom general anaesthesia would be associated with higher morbidity and mortality.

In a double-blind, randomized, placebo-controlled study, 86 patients (44 verum, 42 placebo), scheduled for knee-joint arthrotomies or minor orthopaedic operations received either naproxen, a nonsteroidal antiinflammatory analgesic, or placebo orally in three doses: the first immediately before the operation and the others 6 h and 12 h after the first. The verum group received 1250 mg naproxen in total. Postoperative pain intensity was measured by the category splitting procedure. All patients were allowed to self-administer piritramide from a PCA (patient-controlled analgesia) pump (Prominjekt, Pharmacia, Sweden) in 2-mg boluses every 5 min during a 6-h period and subsequently every 15 min for another 18 h after surgery. The patients receiving verum had significantly (P<0.05) less pain immediately after surgery and used a significantly lower cumulated dose of piritramide during the first 24 h after operation (24 mg vs 44 mg;P<0.05) than placebo-treated subjects. There were no significant differences in the incidence of side-effects between the two groups. The intensity of typical side effects of opioids and antipyretic anti-inflammatory analgesics (nausea, vomiting, stomachache, headache, vertigo) was low and they were easily controlled in all cases. Lowering of respiratory frequency was not observed. Perioperative administration of the nonsteroidal anti-inflammatory analgesic naproxen results in better pain relief and significantly lower opioid requirements (by about 46%) after minor orthopaedic surgery.

In a double-blind, randomized, placebo-controlled study, 112 patients scheduled for knee-joint arthrotomies or minor orthopaedic operations received 75 mg diclofenac, 600 mg apazone, the combination of 75 mg diclofenac and 600 mg apazone, or placebo (50 ml NaCl 0.9%) as a single i.v. dose immediately after operation. Postoperative pain intensity was measured by a numeric rating scale. All patients were allowed to self-administer piritramide from a PCA (patient-controlled analgesia) pump (Prominjekt, Pharmacia, Sweden) in 2-mg boluses every 5 min during the first 6 h and subsequently every 15 minfor another 18 h after surgery. The patients receiving diclofenac, apazone, or the combination of diclofenac and apazone required a significantly lower cumulated dose of piritramide during the first 24 h after operation than did placebo-treated subjects (38 mg vs 39 mg vs 27 mg vs 67 mg;P<0.05), but there were no significant differences among the former three groups of patients. The incidence of typical side effects of opioids and antipyretic anti-inflammatory analgesics (nausea, vomiting, stomach ache, headache, vertigo) was low, and they were easily controlled in all cases. Postoperative combined application of the nonsteroidal anti-inflammatory analgesics diclofenac and apazone results in a significantly lower opioid requirement (about 60%) after minor orthopaedic surgery. The opioid-sparing effect appears to be superior to that of diclofenac (44%) or apazone (42%) alone, but this was not statistically significant.
