Relationship between plasma neutrophil elastase and respiratory index of patients who had undergone cardiac surgery with cardiopulmonary bypass.
To evaluate the effects of cardiopulmonary bypass (CPB) on the release of polymorphonuclear leukocyte elastase (PMN-E) and postoperative pulmonary function, the perioperative plasma levels of PMN-E in α1-antitrypsin complex (EAC) and hydrogen peroxide concentration in the expired breath were measured in eight patients who underwent cardiac surgery with CPB, and the relationship between EAC levels and the respiratory index (RI) was studied. Although PMN, EAC, and the ratio of EAC to neutrophil (E/N) were elevated significantly after surgery, alveolar-arterial oxygen difference (A-aDO2) and respiratory index (A-aDO2/PaO2) did not change when compared with those of the preoperative period. ⋯ However, there was a significant positive correlation between E/N ratio and respiratory index (r=0.67,P<0.01). Thus excessive release of PMN-E during CPB may be implicated in the etiology of postoperative respiratory dysfunction.

The alpha(2)-adrenoceptor agonist clonidine has analgesic properties comparable to those of opioids after systemic administration. It also has antihypertensive, antiemetic, anxiolytic, sedative and antisialogogue effects and reduces the incidence of shivering. Thus, the pharmacodynamic profile of clonidine seems to suit it quite well for the special problems related to recovery from anaesthesia. ⋯ This paper reviews previous experience with systemic administration of alpha(2)-adrenoceptor agonists for postoperative pain relief. Especially in combination with low-dose opioids, clonidine leads to a similar or even better level of pain relief with significantly reduced adverse side effects compared with opioid mono-therapy, perhaps because different sites of action are addressed and influence nociception. Therefore, balanced postoperative analgesia including alpha(2)-adrenoceptor agonists, therefore seems to be a beneficial addition to differentiated postoperative pain relief.

Introduction Spinal epidural abscess is a rare cause of neurological disability, which is frequently, preceded by local spinal pain. There are only a few case series in the literature and the prognosis for this disease has not improved significantly over the past 50 years. Patients and methods Seven patients were treated neurosurgically with laminectomy and abscess drainage for spinal epidural abscesses from 1991 to 1994. ⋯ Elevated blood sedimentation rates in conjunction with local pain of the vertebral column should direct attention to the possibility of an epidural abscess. Magnetic resonance imaging is the radiological technique of choice for establishment of the diagnosis. Conventional X-rays are of no value for early diagnosis because neurological signs and symptoms precede bony changes of the vertebrae.

Postoperative pain therapy often appears to be inadequate in children. The present study was a retrospective investigation of the administration of analgesics given to 133 children and adults following surgery for funnel chest between 1983 and 1994. ⋯ Children received smaller quantities of narcotics than adults when postoperative analgesia was performed with PRN administration. PCA led to delivery of larger quantities of narcotic drugs than PRN medication in children.
