[Post-traumatic hematoma of the esophagus]. / Hématome post-traumatique de l'oesophage.

A 20-year-old man was admitted after a traffic accident for a closed chest trauma. Initial evaluation showed a sternal fracture with a minor pneumomediastinum. Twenty-four hours later be experienced an acute respiratory failure, due to total left pulmonary atelectasis from indirect compression of the left main stem bronchus. Mediastinal widening at the postero-superior level was visualized by CT scan. The aortogram was normal. Thoracotomy showed a moderate left haemothorax, associated with an intramural haematoma of the low thoracic oesophagus which was respected. The time course was uneventful, except repetitive atelectases treated by fibrescopic aspiration. Oesophageal haematoma secondary to chest trauma is a rare injury, with around 10 cases reported in the literature. Compression of tracheobronchial axis is exceptional. Because of the delayed occurrence of such a complication after chest trauma, with sternal fracture, close clinical surveillance and CT scans are essential.

Continuous epidural infusion of ropivacaine for postoperative analgesia after major abdominal surgery: comparative study with i.v. PCA morphine.

We have compared the quality of three regimens of postoperative analgesia (continuous epidural administration of ropivacaine (Ropi. group), epidural ropivacaine and patient-controlled analgesia (PCA) with i.v. morphine (Ropi. + PCA group) and PCA morphine alone (PCA group)) during the first postoperative 24 h in a multicentre, randomized, prospective study. Postoperative analgesia was studied in 130 patients after major abdominal surgery performed under general anaesthesia. The ropivacaine groups received 20 ml of epidural bolus ropivacaine 2 mg ml-1 via the epidural route at the end of surgery, followed by continuous infusion of 10 ml h-1 for 24 h. The Ropi. + PCA group also had access to i.v. PCA morphine 1 mg, with a 5-min lockout. The PCA group received morphine as the sole postoperative pain treatment. The two ropivacaine groups had lower pain scores (P < 0.01) than the PCA group. Morphine consumption was higher in the PCA group (P < 0.05) than in the two ropivacaine groups. The quality of pain relief was rated as good or excellent in 79-85% of patients in the three groups. The percentage of patients without motor block increased between 4 and 24 h from 61% to 89% in the Ropi. group, and from 51% to 71% in the Ropi. + PCA group.

[Indications and role of albumin for vascular loading during postoperative intensive care]. / Indications et place de l'albumine dans le cadre du remplissage vasculaire en réanimation postopératoire.

Prospective clinical trials comparing human albumin to other plasma volume expanders during the three first postoperative days in adult patients were analysed. Fifteen studies were selected. Nine of them concerned the evaluation during the immediate postoperative period, after cardiac surgery with cardiopulmonary bypass (CPB). Only one trial referred to hyperoncotic albumin and therefore did not allow to produce recommendations. However, a priori hyperoncotic albumin should not be used for plasma volume expansion. All other studies compared isooncotic albumin to crystalloid or hydroxyethylstarches (HES). It is concluded that albumin can be recommended neither after vascular (aortic abdominal surgery), nor abdominal surgery and can be replaced by Ringer lactate solution in a volume 1.5 to 2 times higher than with albumin. After cardiac surgery, mainly uncomplicated coronary artery bypass graft or valve replacement, albumin can be substituted by HES. These conclusions are only valid for blood losses below 50% of blood volume. The place of isooncotic albumin for fluid resuscitation in case of blood loss exceeding 50% of blood volume cannot be specified.
