Patients with severe ARDS have a favourable outcome when treated with ECMO and when an ECMO retrieval team establishes the ECMO treatment at the referring hospital. SAPS-II, SOFA and Murray scores predicted the outcome.

Due to wide limits of agreement and different recovery courses, acccleromyographic and mechanomyographic recordings of neuromuscular transmission cannot be used interchangeably. The substantial variation between simultaneous mechanomyographical recordings of neuromuscular transmission obtained in contra lateral arms suggests that this factor should be taken into account when studying new neuromuscular monitoring techniques using the two-arm technique.

Pulmonary endarterectomy has been successfully implemented in Denmark. The perioperative mortality was reduced over time to 9% during the past 5 years. Functional outcome and long-term survival were excellent stressing the importance of surgical treatment for chronic thromboembolic pulmonary hypertension.

The effect of epidurally administered bupivacaine on duration, intensity and reversal characteristics of atracurium-induced neuromuscular blockade was studied in 30 healthy patients anaesthetized with thiopentone, fentanyl, midazolam and nitrous oxide. Fifteen patients received, in addition, epidural anaesthesia with bupivacaine. The remaining patients served as controls. The ulnar nerve was stimulated at the wrist and the evoked twitch response from the adductor pollicis was measured with a force displacement transducer. Neuromuscular blockade was induced with atracurium 0.5 mg i.v. and maintained with repeated doses of atracurium 0.15 mg/kg whenever the twitch height had recovered to 15% of the initial twitch height. After operation, the neuromuscular blockade was reversed with neostigmine when the twitch height had recovered to 15%. In the epidural group the clinical duration of neuromuscular blockade, time until first response to train-of-four (TOF) and reversal time were all significantly prolonged (P less than 0.05). Post-tetanic count (PTC) after 20 min was also significantly lower in the epidural group (P less than 0.05). It is therefore concluded that epidurally administered bupivacaine prolongs atracurium-induced neuromuscular blockade. The clinical implication of the modest prolongation is, however, limited.
