Comparison of preoperative pain and medication use in emergency patients presenting with irreversible pulpitis or teeth with necrotic pulps.

OBJECTIVE: This retrospective study compared differences in preoperative pain and medication use in patients with moderate to severe pain who sought emergency endodontic care for teeth with irreversible pulpitis and for symptomatic teeth with necrotic pulps. STUDY DESIGN: A total of 323 patients seeking emergency endodontic treatment completed questionnaires regarding their biographical information, pain, pain history, and medications. Teeth were tested for vitality, mobility, percussion, and palpation pain. Lymphadenopathy was also evaluated. RESULTS: Patients with irreversible pulpitis waited significantly (P <.05) longer before seeking emergency care (9 days vs 4 days) than patients with symptomatic teeth with necrotic pulps. No differences (P >.05) were found between the groups in terms of analgesic or antibiotic use and pain relief from preoperative narcotic medications. Nonnarcotic analgesics were reported to significantly reduce pain more often in patients with symptomatic teeth with necrotic pulps. There were sex differences in the group of patients with irreversible pulpitis: More women than men were taking analgesic medications and, in the group having symptomatic teeth with necrotic pulps, more men than women reported pain relief from their analgesic medications. CONCLUSION: Patients with irreversible pulpitis wait longer to seek emergency treatment. A majority (81%-83%) of emergency patients with moderate to severe pain will have taken some type of medication(s) to help control their pain, and more women than men with irreversible pulpitis will take an analgesic. By taking their preoperative medication(s), this group of patients will get relief 62% to 65% of the time; furthermore, more men than women with symptomatic teeth with necrotic pulps will experience pain relief.

Percutaneous alcoholization of the celiac plexus under echographic guidance: an alternative to splanchnicectomy? Study of 21 cases

Celiac plexus block is usually performed under fluoroscopic or tomodensitometric guidance. We report on a new procedure using sonographic guidance. The patient lies in supine position. We use a real-time sonograph (Kontron Sigma 1 AC) with a 3.5 MHz probe. On a transverse plane, the celiac axis is localized emerging from aorta. After local anesthesia, the tip of the spinal needle (177 mm, 22 G) is placed close to aorta (about 5 mm) on both sides. 10 to 15 ml of 1 per cent lidocaine then 10 to 15 ml of absolute alcohol are injected on each side. 21 patients (10 males, 11 females, mean age: 61) underwent the procedure. They presented with cancer of the pancreas in 14 cases, metastatic nodes in 3 cases, cholangiocarcinoma in 2 cases and chronic calcifying pancreatitis (CCP) in 2 cases. No pain relief occurred in 3 patients (14 per cent). On of those presented with CCP but the endoscopic cystic diversion of a small cyst was successful to eradicate pain. Partial pain relief occurred in 5 cases (24 per cent). Total pain relief was obtained in 13 cases (62 per cent). No complication related to the treatment was observed. Sonography is a simple and safe method of guidance to perform alcohol block of the celiac plexus. The anterior approach may prevent neurologic complications related to other methods of guidance.

A randomized, placebo controlled, trial of preoperative sustained release Betamethasone plus non-controlled intraoperative Ketorolac or Fentanyl on pain after diagnostic laparoscopy or laparoscopic tubal ligation [ISRCTN52633712].

BACKGROUND: Gynecological laparoscopic surgery procedures are often complicated by postoperative pain resulting in an unpleasant experience for the patient, delayed discharge, and increased cost. Glucocorticosteroids have been suggested to reduce the severity and incidence of postoperative pain. METHODS: This study examines the efficacy of a sustained release betamethasone preparation to reduce postoperative pain and the requirement for pain relief drugs after either diagnostic laparoscopy or tubal ligation. Patients were recruited, as presenting, after obtaining informed consent. Prior to surgery, patients were randomly selected by a computer generated table to receive either pharmacy-coded betamethasone (12 mg IM Celestone trade mark ) or an optically identical placebo injection of Intralipid trade mark and isotonic saline mixture. The effect of non-controlled prophylactic intraoperative treatment with either fentanyl or ketorolac per surgeon's orders was also noted in this study. Blood samples taken at recovery and at discharge times were extracted and analyzed for circulating betamethasone. Visual analog scale data on pain was gathered at six post-recovery time points in a triple blind fashion and statistically compared. The postoperative requirement for pain relief drugs was also examined. RESULTS: Although the injection achieved a sustained therapeutic concentration, no beneficial effect of IM betamethasone on postoperative pain or reduction in pain relief drugs was observed during the postoperative period. Indeed, the mean combined pain scores during the 2 hour postoperative period, adjusted for postoperative opioids as the major confounding factor, were higher approaching statistical significance (P = 0.056) in the treatment group. Higher pain scores were also observed for the tubal ligation patients relative to diagnostic laparoscopy. Intraoperative fentanyl treatment did not significantly lower the average pain score during the 2 hour postoperative period. Intraoperative ketorolac treatment significantly lowered (P = 0.027) pain scores and reduced the postoperative requirement for additional pain relief drugs. CONCLUSIONS: There was a lack of efficacy of preoperative sustained release betamethasone in reducing postoperative pain despite maintaining a therapeutic concentration during the postoperative period. Intraoperative Ketorolac did afford some short-term pain relief in the postoperative period and reduced the need for additional pain relief drugs.

A survey of pain relief clinics in the South Western Region.

All the district general hospitals in the South Western Health Region have a pain relief service in existence or planned for the immediate future. Almost all are recognized by the allocation of anaesthetic consultant sessions. In most cases, this allocation is less than the time required for pain relief. All the consultants concerned work in single disciplinary clinics and accept both in-patient and out-patient referrals. They provide an advisory and therapeutic service to patients in the care of other clinicians and give tuition, mainly to junior anaesthetists. Most also undertake domiciliary assessment and treatment. In most clinics the pain relief Service is hampered by inadequate facilities. The minimum facilities for a basic efficient service are here reviewed.

Chronic pancreatitis: results of a protocol of management.

Thirty-five patients with chronic pancreatitis of varying cause have been treated according to a protocol first introduced in 1979. At the end of a mean follow up time of 2.1 years, only 54% of patients were found to have derived benefit defined by pain relief and improved quality of life. Patients with alcoholic pancreatitis did particularly poorly, and alcoholics who continued to drink almost never benefited. Patients with dilated pancreatic ducts were more likely to do well than those with small ducts, and pancreaticojejunostomy had a satisfactory record of pain relief. Patients with biliary pancreatitis generally did well with cholecystectomy and clearance of the common bile duct. The 40-80% pancreatectomy had a poor record for pain relief, and produced diabetes in the majority of patients in whom it was used. Nothing will reverse the established pathology of chronic pancreatitis, which remains an unsatisfactory condition to treat.

Orthotic therapy in the management of osteoarthritis.

The authors evaluate the use of orthoses as a primary therapeutic means in the long-term management of patients with osteoarthritis of the foot and ankle. A comparison of the amount of pain relief experienced by 64 subjects (mean age 63 years) with different treatment regimens for osteoarthritis was made to determine the role orthoses played in helping to reduce or eliminate pain. One hundred percent of the subjects wearing orthoses only for relief of pain had a statistically significant longer period of pain relief than those on nonsteroidal anti-inflammatory drugs. Fifty-five percent of the subjects using orthoses and nonsteroidal anti-inflammatory drug therapy also had a statistically significant longer period of pain relief than those receiving nonsteroidal anti-inflammatory drug therapy only.

Trigeminal neuralgia: what are the important factors for good operative outcomes with microvascular decompression.

BACKGROUND: Microvascular decompression has been widely used as the first choice in treating trigeminal neuralgia, but in a few patients, facial pain cannot be effectively controlled by microvascular decompression. We sought to clarify the important factors for good operative outcomes. METHODS: We reviewed 62 patients with trigeminal neuralgia treated by microvascular decompression during the period 2000 through 2002, including clinical presentation, operative findings, techniques, and outcomes. Neurovascular conflicts were divided into single contact, contact and indentation, single adhesion, adhesion and indentation, and trigeminal nerve atrophy. Operative outcomes were graded into immediate postoperative complete pain relief (excellent), delayed postoperative complete pain relief (better), significant pain relief (good), and no response to microvascular decompression (poor). RESULTS: All patients' presentations were typical at the time of pain onset, but the symptom in 17 patients changed to atypical before surgery. During operation, single contact and single adhesion was found in 14 patients and 15 patients, respectively; contact or adhesion in combination with indentation was found in 7 patients and 18 patients, respectively; atrophy occurred in 8 patients. Postoperatively, immediate and delayed complete pain relief was achieved in 32 (51.6%) patients and 17 (27.4%) patients, respectively; 11(17.7%) patients got significant pain relief; and 2 patients showed no response. The overall rate of complete pain relief in patients with shorter duration, typical presentation, artery compression and complete decompression was higher than that in patients with longer duration, atypical presentation, venous compression, and incomplete decompression. CONCLUSIONS: Shorter duration, typical presentation, single artery compression, and complete decompression are the positive factors for better operative outcomes with microvascular decompression. Worse outcomes are usually related to venous compression, longer duration, and atypical presentation.

Outcomes for surgical management of orchalgia in patients with identifiable intrascrotal lesions.

OBJECTIVE: The outcome of surgery for relief of orchalgia in patients with identifiable intrascrotal pathology is not well defined. We evaluated the success of commonly performed surgical procedure indicated for pain relief in patients with specific intrascrotal lesions. METHODS: Surgical cases performed for relief of painful scrotal pathology were reviewed, including ligation of internal spermatic vein, hydrocelectomy, spermatocelectomy, and orchiopexy for suspected intermittent torsion. Relief of pain as reported to the physician and time for return to full activity were determined. pain relief was compared to a 50% placebo rate using Fisher's exact test. RESULTS: Eigthy-five of 151 patients (56%) undergoing surgery for pain relief had complete data and adequate follow-up for analysis. Of 40 patients who had ligation of the internal spermatic vein, 30 (75%) were relieved of pain (p = 0.037). All 19 patients with painful hydroceles and 16 of 17 (94%) with spermatoceles were relieved of pain (p < 0.001). Of 9 patients undergoing scrotal orchiopexy for suspected intermittent torsion, 8 (89%) were pain-free (p < 0.001). CONCLUSION: Surgical management of specific intrascrotal lesions is highly effective.

The efficacy and complications of laparoscopic presacral neurectomy in pelvic pain.

OBJECTIVE: To evaluate the efficacy and complications of laparoscopic presacral neurectomy in pelvic pain. METHODS: We reviewed records of 655 patients receiving laparoscopic conservative surgery and laparoscopic presacral neurectomy for diagnoses including adenomyosis with dysmenorrhea (n = 55), moderate and severe endometriosis with dysmenorrhea (n = 127), minimal and mild endometriosis with dysmenorrhea (n = 208), primary dysmenorrhea (n = 99), and chronic pelvic pain with or without pathologic disease (n = 166). pain relief was evaluated at least 12 months postoperatively. RESULTS: pain relief was evaluated in 527 patients. Significant pain relief (no pain or mild pain requiring no medication) was found in 22 (52%) of 42 women with adenomyosis, in 75 (73%) of 103 with moderate to severe endometriosis with dysmenorrhea, in 123 (75%) of 164 with minimal to mild endometriosis with dysmenorrhea, in 64 (77%) of 83 with primary dysmenorrhea, and in 84 (62%) of 135 with chronic pelvic pain. There were four major complications (0.6%) that required further surgery, including injury of the right internal iliac artery (n = 1) and chylous ascites (n = 3). Three cases (0.5%) had laceration of the middle sacral vein controlled during laparoscopy. In addition, 485 (74%) of the 655 patients complained of constipation after laparoscopic presacral neurectomy, which was relieved easily by medication. CONCLUSION: Presacral neurectomy can be performed safely and efficiently by laparoscopy and is a valuable alternative treatment for pelvic pain.

Electrical stimulation in chronic low-back pain.

Since 1972, 367 patients with chronic low-back pain have been treated by electrical stimulation (e.s.). Patients with herniated disc lesions and spondylitis and allied conditions were included. Following e.s. 75-100% pain relief was obtained by 53% of the patients 50% pain relief by 27% and there was no improvement in 20% of patients. In a follow-up of 208 patients, 6-36 months later, approximately 70% stated that pain relief was similar to that obtained at the end of treatment.
