Review Case Reports[Iterative epidural anesthesia after accidental dural puncture. Analysis with epidurography].
The case is reported of a 63-year-old man who was to undergo a gastrectomy for stomach carcinoma. An epidural catheter for postoperative analgesia (epidural morphine) was inserted into the T10-11 space prior to induction of general anaesthesia. Unfortunately, cerebrospinal fluid (CSF) surged back through the Tuohy needle, which was immediately withdrawn. ⋯ Another epidurography, 24 hours later, showed the same picture. The analgesic technique was therefore altered to subcutaneous buprenorphine. Careful management of this situation, in order to prevent total spinal anaesthesia, is discussed in the light of the literature.

Review Randomized Controlled Trial Comparative Study Clinical Trial[Prevention by naloxone of adverse effects of epidural morphine analgesia for cancer pain].
Forty cancer patients were randomly assigned to two groups (n = 20). All had incapacitating pain unresponsive to the usual non opioid analgesic drugs. An epidural catheter was set up at the level of the most painful metamere, and made to pass subcutaneously so as to exit either in the supraclacicular fossa, or on the patient's flank. ⋯ There was no statistically significant difference between the groups in quality and duration of analgesia. Pain reached its lowest level 4 h after the injection of morphine, returning to half its original value at the 24th h. This was also true for the incidence of nausea (11 in group N, 5 in group P), vomiting (3 in both groups), and urinary retention (6 in group P, 5 in group N).(ABSTRACT TRUNCATED AT 250 WORDS)

Patient controlled analgesia (PCA) is a drug delivery system aimed to control acute pain using negative feedback technology in a closed loop system in which the patient plays an active role. It overcomes the inadequacies of traditional analgesic protocols due to marked differences in pharmacokinetic and dynamy of analgesis between patients. Moreover, doctors and nurses frequently underprescribe opioids in patients with severe pain for fear of dangerous side-effects. ⋯ The principles of demand analgesia are now being investigated using other agents, such as local anaesthetics, and other routes of administration, mainly epidural injection. In most patients, even in children, PCA can replace intramuscular injections, which are the standard route for opioid administration. Today PCA and spinal opioids are the two main methods of analgesia for postoperative pain management.

Review Case Reports[Accidental epidural injection of hypertonic sodium chloride solution].
Twenty ml of 20% hypertonic saline were accidentally injected into the epidural space of a 53-year-old man with lumbar backache and sciatica. This resulted in severe thoracolumbar pain, which disappeared after he received by the same route 20 ml of 1% lidocaine and 40 ml distilled water. ⋯ A literature survey helped to explain the signs described. Further cases of accidental epidural injections of other drugs are discussed.

Single lung transplantation was performed in several steps: laparotomy to prepare an omentopexy, followed by pneumonectomy and implantation of a pulmonary graft, both by postero-lateral thoracotomy. The patients suffered from lymphangiomyomatosis (1), panacinar emphysema (2) and idiopathic pulmonary fibrosis (1). Immunosuppressive treatment was started before surgery. ⋯ Except in one patient with preoperative pulmonary hypertension, the increase in pulmonary vascular resistances remained moderate after clamping of the pulmonary artery. Sufficient oxygen delivery, with more than 50% venous oxygen saturation, was maintained at this time by the infusion of dopamine and dobutamine. Two other specific problems were encountered in the emphysematous patients: severe hypotension following the start of artificial ventilation and after placing the patient in lateral position; thoracic asymetry with overdistension of the emphysematous lung, and mediastinal shift.(ABSTRACT TRUNCATED AT 250 WORDS)
