[Complaints in the postoperative phase related to anesthetics].

In two prospective, randomized studies the frequency of headache, nausea, vomiting, and analgesic requirement during the first postoperative 24 h was observed in order to study differences between the sexes and the inhalation anesthetics halothane, enflurane, isoflurane, or balanced anesthesia with enflurane/alfentanil. Nausea and vomiting were more frequent after enflurane than after halothane or isoflurane. There was no significant difference between anesthetics and frequency of headache, but there were significant differences in postoperative analgesic requirements which were highest after halothane and lowest after isoflurane. Postoperative complaints were always significantly greater among women than among men. The second study indicated that balanced anesthesia did not reduce the analgesic requirement compared to enflurane without alfentanil, but lead to a higher incidence of vomiting. After premedication with flunitrazepam and atropine and combined with 70% N2O/30% O2, isoflurane was the most favorable anesthetic agent with regard to the parameters studied. Balanced anesthesia with enflurane/alfentanil did not show any advantages for patients in the postoperative phase under the given conditions.

[Success rate and complications of a modified retrograde intubation technic in 36 patients].

The main disadvantage of guided blind intubation (Waters technique) is injury to the mucous membrane and cartilaginous skeleton of the larynx. Thirty-six patients scheduled for laryngectomy were intubated using a modified Waters technique. The practicability of this technique as well as the type and extent of damage to the laryngeal tissue were evaluated under controlled conditions. Intubation was successful in 35 patients (first attempt, 31 patients; 2-3 attempts, four patients). A stenosing carcinoma of the larynx required a tracheotomy in the remaining patient. No serious damage to the mucous membrane or cartilage was demonstrated in the 26 controlled resected larynges. In a difficult intubation, the guided blind technique is a possible alternative because of the relatively low extent of damage and technical requirements; maintenance of spontaneous respiration is not required.

[Long-term intubation following tracheotomy].

Between 1981 and 1983 tracheotomy was performed on 61 patients in the Surgical University Clinic of Tübingen. The dominant factors in indication of tracheotomy was for 49% of patients the persistingly necessary artificial respiration, for 26% a better bronchial toilet and other reasons for 25%. With 40.5% of all cases pneumonia was the most frequent complication encountered with our patients. The most frequent bacteria was Pseudomonas aeruginosa. Because of the decisive advantage constituted by the possibility of unproved bronchial toilet an earlier realisation of tracheotomy is to be recommended.

[Cardiorespiratory problems in the use of calcium antagonists for vasospasm prophylaxis in subarachnoid hemorrhage].

Since studies by Allen et al. [1] calcium antagonists have been commonly used for prevention of cerebral vasospasm in patients suffering from acute subarachnoid hemorrhage (SAH). Vasodilatation-induced hypotension, increase of cardiac output and intrapulmonary shunting (Qs/Qt) are wellknown cardiovascular effects. These problems are discussed in light of previous reports and present case study of a 34-year-old woman treated with the calcium antagonist nimodipine after SAH. Reproducible results from invasive haemodynamic monitoring (Swan-Ganz-thermodilution catheter) indicated correlation between nimodipine application and increased intrapulmonary shunting. This effect can be hazardous for SAH patients because preexisting cerebral ischemic hypoxia makes them particularly susceptible to additional decrease in oxygen supply.

[Results of therapy of severe metabolic alkalosis using hydrochloric acid infusions].

Severe metabolic alkalosis is often treated by infusion of arginine-HCl. Since we know that this substance leads to a supplemental increase of intracellular pH and fails to reduce intracellular bicarbonate concentration we use HCl for correction of this disturbance of acid-base equilibrium. 18 intensive-care patients with severe metabolic alkalosis were treated with an infusion of 0.2 m HCl. While base excess and sodium decreased significantly, chloride increased slightly. Arterial plasma pH, potassium, Hb, Hk, pCO2, pO2, and SO2 remained unchanged. Instructions for preparing different HCl solutions and advice on dosage are given.
