Longterm treatment with epidural opioids. A retrospective study comprising 150 patients treated with morphine chloride and buprenorphine.

During a 2-year period, 150 patients were treated with epidural opioids for more than 7 days; 89 received morphine and 61 buprenorphine. In 16 cases, medication was changed from morphine to buprenorphine, and in 6 from buprenorphine to morphine. In 19 patients in each group, the disease process was benign. The median daily dose of morphine was 17 mg given by an average of 2.9 injections; the corresponding figures in the buprenorphine group were 1.3 mg and 2.6 injections. The mean duration of treatment was 49 days (7-397) in the morphine group and 53 days (7-262) in the buprenorphine group. Satisfactory pain relief was achieved in 40 (45%) patients who received morphine and 41 (67%) patients given buprenorphine. Altering medication from morphine to buprenorphine improved analgesia in 32% of patients, while the reverse improved pain relief in a further 46% of the patients. Side effects were reported in 46% of patients given morphine and 20% given buprenorphine. Seventy-one patients were treated on an outpatient basis. In these cases, buprenorphine was administered for 89% of the total duration of treatment and morphine chloride for 52%.

Potentiation of epidural opioids with epidural droperidol. A one year retrospective study.

During a period of one year, 119 patients with chronic pain received injections of opioids via a catheter inserted in the lumbar epidural space. Twenty-three patients (19%) showed evidence of tolerance and were given droperidol 1.25-5.0 mg epidurally. In 20 patients in this study, there was a significant reduction in the number of epidural opioid injections. Six patients complained of excessive sedation, which disappeared when the dose of droperidol was reduced, although this did not affect the analgesia. One patient given an accidental overdose of droperidol developed reversible Parkinsonism. It is concluded that epidural administration of the dopamine antagonist droperidol may be beneficial as supplementary medication to epidural opioids when tolerance develops.

A fatal case of malignant hyperthermia following isoflurane anaesthesia.

To date, only two cases of malignant hyperthermia following isoflurane anaesthesia have been reported, neither of which were fatal. This case describes a very malignant form of hyperthermia after isoflurane, in which the laboratory values were grossly abnormal, and with multi-organ failure and death finally supervening.

Clinical and experimental evaluation of cefoxitin therapy.

30 patients were treated with i.v. cefoxitin (4-8 g/day), of which 20 had documented infections which included endocarditis (5), lung abscess (4), empyema (4), liver and subhepatic abscess (3), osteomyelitis (3), and pancreatic abscess (1). 14 patients had infections caused by anaerobic bacteria and 5 had endocarditis due to aerobic organisms. All but 2 patients with osteomyelitis of the mandible were cured. Adverse reactions were noted in 7 patients, mostly due to drug fever and leukocytosis; one had Coombs'-positive hemolytic anemia. The average serum cefoxitin levels were 24, 16, 12, and 4 microgram/ml at 1, 2, 3 and 4 h, respectively, and the average serum/pleural fluid ratio was 1:0.5 +/- 0.25. All anaerobic and aerobic isolates except one strain of Bacteroides fragilis were susceptible to cefoxitin at less than or equal to 32 microgram/ml. The concentration of cefoxitin in the tissues was measured in 8 rabbits; it was 4 +/- 1 microgram/ml in the heart and 2 +/- 0.5 microgram/ml in the femur and mandibular tissue, suggesting that the lack of response in cases of osteomyelitis could be due to inadequate antibiotic concentration in the bone. Our study suggests that cefoxitin can be used in the treatment of anaerobic infections and endocarditis due to susceptible organisms.

Cyclacillin: in vitro activity against aerobic and anaerobic bacteria.

Cyclacillin at 50 microgram/ml inhibited streptococci (100%), shigella (72%), and Bacteroides (B) fragilis ss fragilis (84%). At 100 microgram/ml it inhibited proteus (75%), B. fragilis (86%), and E. coli (50%). Cyclacillin was more effective than ampicillin against beta-lactamase-producing H. influenzae. The activity of cyclacillin was found to be more enhanced when tested in nutrient agar and Mueller-Hinton agar than in brain heart infusion agar.

In vitro activity of ticarcillin against anaerobic bacteria compared with that of carbenicillin and penicillin.

A total of 334 clinical anaerobic isolates were tested in an anaerobic glove box by the agar dilution technique for susceptibility to clinically achievable levels of ticarcillin, carbenicillin, and penicillin. Thirty-two micrograms or less of penicillin per milliliter inhibited 91% of all strains, whereas 100 mug of carbenicillin and ticarcillin per ml inhibited 95 and 98%, respectively. A total of 82% (85 strains) of Bacteroides were inhibited by penicillin, and 93 and 96% were inhibited by carbenicillin and ticarcillin, respectively. Thirteen (24%) of 55 strains of Bacteroides fragilis tested were resistant to 32 mug of penicillin per ml, and 6 (11%) and 3 (5%) were resistant to 100 mug of carbenicillin and ticarcillin per ml, respectively. Within the therapeutic range, ticarcillin was the most effective of the three penicillins tested against B. fragilis subsp. fragilis.
