    Notes: Summary Antacids can modify the pharmacokinetic parameters of sustained-release preparations of theophylline by changing the gastric pH. Though this has been studied with various theophylline/antacid combinations, the specific preparations investigated here have not previously been tested. The objective of the study was to assess any change in the availability of theophylline from a sustained-release preparation (SR), induced by the coadministration with an antacid. The study was designed as a double-blind randomized crossover trial in the Pneumology Departments of three general hospitals. Fifteen patients were studied. They all had stable asthma treated with theophylline and no major organ failure or gastro-intestinal lesions requiring the use of antacids. The antacide (aluminium hydroxide 800 mg and magnesium hydroxide 800 mg), or placebo, tid, was added to a stable regimen of theophylline SR bid, for 4 days, in crossover fashion. Plasma theophylline concentrations were measured before and 1,2,3,4,6,8,10,12,16 and 24 h after the morning dose of Armophylline on the fourth day of each treatment period; the maximum plasma concentration (Cmax), and time to Cmax (tmax) were noted, and the area under the 24-h time-concentration curve (AUC0–24) and mean plasma concentration (Cmean) were computed. Peak expiratory flows on the same day, before and 3, 6 and 12 h after the morning dose of Armophylline were also measured. There was no change in any of the parameters studied. The addition of the antacide to theophylline, each given according to standard clinical practice, did not modify the pharmacokinetics of the latter. This result probably can not be generalized to all pairs of sustained-release theophylline-antacid preparations.

    Notes: Summary The present study is a comparison of the pharmacokinetics of four local anaesthetics injected double blind in the right subdiaphragmatic area during outpatient laparoscopy performed under standard general anaesthesia in 28 young women. 80 ml of one of the following solutions was injected: Group A 0.5% plain lidocaine (n=7), Group B 0.5% lidocaine with 1/320.000 adrenaline (n=8), Group C 0.5% lidocaine with 1/800.000 adrenaline (n=7), and Group D 0.125% bupivacaine with 1/800.000 adrenaline (n=6). Blood samples were collected over 360 min from an iv catheter and serum concentrations were measured by gas chromatography. No adverse effects occurred in the study period. In Group A (plain lidocaine), Cmax was significantly higher and tmax significantly earlier than in Groups B and C (lidocaine with adrenaline). A toxic level was not found after either solution in any patient. The intraperitoneal use of doses of 400 mg lidocaine or 100 mg bupivacaine for perioperative analgesia was safe and solutions of lidocaine containing adrenaline appeared to pose even less risk than plain solutions.

    Notes: Laparoscopic surgery carried out under general anaesthesia is associated with physiological changes, which also determine changes in intra-ocular pressure. We measured intra-ocular pressure at each phase of gynaecological laparoscopy, carried out under propofol-alfentanil-isoflurane general anaesthesia, in young women of ASA 1 status, with no pre-existing eye disease. Measurements were made with a Perkins applanation tonometer. Mean arterial pressure and end-tidal CO, tension were kept constant throughout the study. Intra-ocular pressure decreased significantly after induction of anaesthesia, remained unchanged after a pneumoperitoneum of up to an intraperitoneal pressure of 15 mmHg had been created, increased significantly with head down tilt, but did not increase significantly above pre-induction values. Adequate depth of anaesthesia compensated for the intra-ocular pressure increase caused by head down position. Plateau airway pressure, considered as reflecting intrathoracic pressure, increased with intraperitoneal pressure elevation. However, such changes did not correlate with intra-ocular pressure changes.

    Topics: Medicine
    Notes: We assessed the peri-operative analgesic efficiency of low-dose intrathecal morphine combined with a low dose of bupivacaine after elective laparoscopic cholecystectomy since postoperative pain in such procedures, although less than after a conventional open technique, may be significant, particularly during the first 12–24 h. After informed consent, 34 ASA I or II patients were randomly allocated to one of two groups to receive either a lumbar intrathecal injection of morphine (75 or 100 μg) combined with 5 mg of isobaric bupivacaine (spinal group) or a subcutaneous injection of a saline solution (control group). Intra-operatively, opioid requirements, blood pressure response and heart rate changes after insufflation were recorded. Postoperatively, morphine requirements, pain scores and opioid-related side-effects were assessed by a physician blinded to the randomisation. Intra-operative opioid requirements did not differ significantly between groups. Mean (SD) postoperative morphine requirements were significantly lower in the spinal group [13 (10) vs. 23 (10) mg; p = 0.04] as were postoperative pain scores (p 〈 0.001). Side-effects were of comparable incidence and severity between groups. Low-dose intrathecal morphine combined with low-dose bupivacaine provided effective postoperative analgesia for elective laparoscopic cholecystectomy.

    Notes: We report a case of Streptococcus salivarius meningitis following combined spinal–epidural analgesia for labour. Although rare, bacterial meningitis following combined spinal–epidural anaesthesia is being increasingly described. We review the previously reported cases and discuss the possible aetiological causes and the aseptic precautions likely to reduce the incidence of infectious complications.

    Notes: Background: Morphine is widely used in association with local anaesthetics for postoperative epidural analgesia. There are no data on the prolonged use of clonidine for postoperative analgesia in children. The primary outcome of this randomized, double-blind trial was to compare the incidence of side-effects after epidural infusion of clonidine or morphine, in association with ropivacaine in children. Methods: After institutional approval, 26 children, aged 3–12 years, who were scheduled for abdominal surgery, had an epidural catheter placed after induction of general anaesthesia. Patients were then randomized to two different groups. After an initial bolus of 2.5 mg·kg−1 0.25% ropivacaine with either 40 µg·kg−1 morphine (group M, n = 14) or 1 µg·kg−1 clonidine (group C, n = 12), an epidural infusion was started at a rate of 0.4 ml·kg−1·h−1. The patients in the M group received an infusion of 0.08% ropivacaine with 10 µg·ml−1 morphine, those in the group C an infusion of 0.08% ropivacaine with 0.6 µg·ml−1 clonidine. Results: The two groups were similar with respect to age, sex and weight. One patient in the C group was excluded for misplacement of the epidural catheter. The incidence of vomiting and pruritus was significantly higher in the M group compared with the C group (64% and 85% versus 0%, respectively). The incidence of pain was significantly higher in the C group compared with the M group (73% versus 29%) as well as the need for rescue analgesia medications. Conclusions: Epidural clonidine is followed by a significantly lower incidence of side-effects. However, its analgesic effects, at least at the doses used in this study, are less potent than those of epidural morphine.

    Notes: Abstract Background: Increased intraperitoneal pressure in the head-down position is associated with a significant increase in intraocular pressure (IOP) in rabbits with α-chymotrypsin–induced glaucoma. Also, the retinal cells are weakened by the induction of increased IOP, and/or glaucoma, even when IOP is controlled by adequate therapy; therefore, these cells need to be protected from any additional aggression. Actin and vimentin are proteins of the retinal cell cytoskeleton that react readily in response to retinal injuries, including ischemia and glaucoma. Early changes in these cytoskeleton proteins determine the morphological changes observed after retinal damage. Therefore, we set out to investigate intracytoplasmic changes in vimentin and actin after a 4-h CO2 pneumoperitoneum in the head-down position in rabbits with α-chymotrypsin–induced glaucoma. Methods: Twenty-one rabbits with α-chymotrypsin–induced glaucoma in one eye received general anesthesia for 4 h in the head-down position and were randomly allocated to have (a) no pneumoperitoneum, (b) a 10 mmHg CO2 pneumoperitoneum, or (c) a 20 mmHg CO2 pneumoperitoneum. At the end of the trial, both the right glaucomatous and the left control eyes were enucleated and investigated immunocytochemically for alterations in vimentin and actin, and morphologically for retinal layer disorganization. Results: Except for the preexisting morphological changes induced by glaucoma, both the control and the glaucomatous eyes in all rabbits appeared normal in terms of retinal layer organization and the distribution of intracellular vimentin and actin whatever the intraperitoneal pressure level applied. Conclusion: In rabbits with α-chymotrypsin–induced glaucoma, a 4-h CO2 pneumoperitoneum of ≤20 mmHg in the head-down position did not induce either retinal layer disorganization or alteration of actin or vimentin.
