Phenelzine poisoning 总被引:1,自引:0,他引:1
F. X. BREHENY MB BCh BAO FFARCSI FFARACS G. J. DOBB MSc. MB BS MRCP FFARCS G. M. CLARKE MB BS FFARCS FFARACS 《Anaesthesia》1986,41(1):53-56
A 46-year-old female with severe phenelzine poisoning was managed successfully by alpha blockade and fluid loading, with the aid of invasive haemodynamic monitoring. The pathophysiology was documented, showing elevated plasma and urinary catecholamines, cardiovascular abnormalities and a contracted blood volume. Most of these changes were reversed following treatment. 相似文献

Day case laparoscopy: a survey of postoperative pain and an assessment of the value of diclofenac 总被引:8,自引:0,他引:8
N. D. Edwards MB BS FCAnaes K. Barclay MB ChB S. J. Catling BA MB BS FFARCS D. G. Martin BSc MB BCh MRCP FFARCS R. H. Morgan MA MBBChir DObstRCOG FFARCS 《Anaesthesia》1991,46(12):1077-1080
A randomised, controlled study was undertaken to assess the postoperative pain and side effects experienced by patients undergoing day case diagnostic laparoscopy and laparoscopic sterilisation, and to evaluate the effectiveness in these patients of peroperative diclofenac. Patients undergoing laparoscopic sterilisation had significantly higher pain scores at one hour postoperatively, and at discharge, than patients undergoing diagnostic laparoscopy (p less than 0.01) but there were no significant differences in pain scores 24 hours after discharge. The incidence of postoperative side effects following discharge from hospital was high, but there were no significant differences between the groups. Diclofenac had no significant effect in either group on the severity of postoperative pain, or the incidence of postoperative side effects. 相似文献

The systems approach to error reduction: factors influencing inoculation injury reporting in the operating theatre Aim To examine the frequency of, and factors influencing, reporting of mucocutaneous and percutaneous injuries in operating theatres. Background Surgeons and peri-operative nurses risk acquiring blood-borne viral infections during surgical procedures. Appropriate first-aid and prophylactic treatment after an injury can significantly reduce the risk of infection. However, studies indicate that injuries often go unreported. The ‘systems approach’ to error reduction relies on reporting incidents and near misses. Failure to report will compromise safety. Methods A postal survey of all surgeons and peri-operative nurses engaged in exposure prone procedures in nine Welsh hospitals, face-to-face interviews with selected participants and telephone interviews with Infection Control Nurses. Results The response rate was 51.47% (315/612). Most respondents reported one or more percutaneous (183/315, 58.1%) and/or mucocutaneous injuries (68/315, 21.6%) in the 5 years preceding the study. Only 54.9% (112/204) reported every injury. Surgeons were poorer at reporting: 70/133 (52.6%) reported all or >50% of their injuries compared with 65/71 nurses (91.5%). Conclusions Injuries are frequently under-reported, possibly compromising safety in operating theatres. Implications for nursing management A significant number of inoculation injuries are not reported. Factors influencing under-reporting were identified. This knowledge can assist managers in improving reporting and encouraging a robust safety culture within operating departments. 相似文献

Failure to deliver stents is one of the commonest causes of procedural failure in contemporary PCI practice. We describe successful use of the Guideliner Catheter, the first purpose designed FDA and CE marked device delivery catheter in 13 complex cases in native coronary vessels and bypass grafts performed via the radial route to enable distal stent delivery following failure of conventional techniques. We discuss how the Guideliner catheter may be used to facilitate difficult radial cases. © 2010 Wiley‐Liss, Inc. 相似文献

This is a retrospective study on the use of postoperative opioids in neonates admitted to the surgical intensive care unit at Great Ormond Street over a 5-year period (1980-84). A total of 131 (14%) babies received opioids out of 933 neonates admitted to the unit. The use of opioids increased from 9.7% to 27.2% of admitted cases during the survey period. Postoperative ventilation of the lungs was necessary in 240 (25.7%) cases and 88 (36.6%) of these were given opioids. Four babies initially failed to wean from controlled ventilation as a result of opioid induced respiratory depression. A total of 51 (7.35%) spontaneously breathing neonates received opioids and seven (13.7%) of these developed apnoea or respiratory failure thought to be induced by opioids. The administration of opioids by nurses occurred most frequently in the late evening and early hours of the morning, when medical cover is at its lowest level. 相似文献
