[Local anesthesia: contraindications and complications].

The widespread use of local anesthetic agents in connection with minor office and emergency surgery prompted the authors to look into various aspects of this practice. Doubtless, these drugs are extremely handy and constitute a valuable aid in many situations; still, possible complications and contraindications must be clearly assessed. The authors conclude their discussion with an outline of essential things to do in the event of unexpected clinical mishaps.

[Anesthesia for cataract surgery. Result of a national survey].

OBJECTIVES: In order to evaluate the impact of recent progress in anesthesia and cataract surgery, we conducted a national survey in France to determine which techniques are used. METHODS: A questionnaire was sent to the most representative French ophthalmology teams: 66 teams participated in the survey. RESULTS: Seventy-one percent of the surgeons routinely used phacoemulsification: 91% of the anesthesists prefer locoregional anesthesia: contraindications most often involved general health status (89%). Ambulatory anesthesia was preferred by 16.7% of the teams. CONCLUSION: Phacoemulsification under peribulbal anesthesia is currently the technique most frequently used in cataract surgery in France. Ambulatory anesthesia is not yet widely used for this type of surgery.

[Thalassemic syndromes and anesthesia].

Thalassemic syndromes are produced by a quantitative defect in the synthesis of globin chains of hemoglobin. They are classified according to the severity of the clinical picture and to the type of globin chain that is affected. Physiopathology, clinical picture, and treatment of thalassemias are discussed in this work. Thalassemia minor does not create, in general, anesthetic problems. In cases of thalassemia major one should consider not only problems derived from the severity of the anemia it self, but also those related to transfusional therapy, and to bony malformations that may disturb tracheal intubation. Discussion on the management of homozygotic thalassemia during the pre, per, and postoperative phase completes this revision.

[Criteria for selection and contra-indications of ambulatory surgery].

Ambulatory surgery means to us the scheduled surgery and investigations carried out under various modes of anaesthesia in patients who are admitted in the morning and discharged in the evening. Now the strictness and guarantees required and the essential conditions of safety and efficiency can only be achieved if a number of selection criteria and contraindications are complied with. The authors first study the lesions for which ambulatory treatment is possible, as well as the criteria regarding both the patient and the attending physician responsible for the follow-up at home. Since a close co-operation between the anaesthesist and the surgeon proves to be essential, the criteria of anaesthesia must also be dealt with. The contraindications are connected to the type of surgery, to the type of anaesthesia, to the patient, to the patient's circle, to the medical team, and finally to the equipment and organization of the unit in which ambulatory surgery is performed. These many aspects of the problem are analyzed and discussed.

[Ambulatory surgery in the hospital--analysis of a 1978-1994 patient sample].

In the outpatient department of the University hospital of the Technology University Dresden ambulatory surgery has been performed since 1965. The patients of 16 years were analyzed. From 1978 till VI/1994 we have carried out 13948 elective operations. The personal wish of a cooperative patient without risk factors and an orderly social surrounding are the prerequisites for carrying out outpatient operations. Applied anaesthetic techniques were: general anaesthesia 9.2%, spinal anaesthesia 7.1%, sacral anaesthesia 14.8%, nerveblock of the upper extremity 11.1 and infiltration anaesthesia 57.8%. On the day of operation 61 patients had to be admitted to the hospital because of intraoperative events, expansion of the operation and complications of anaesthesia. Between the first to eight postoperative day 23 patients were hospitalised due to bleeding and 1 patient due to a wound infection. After aseptic elective operations 33 patients (0.35%) and after proctology operations with primary wound closure 10% of the patients developed wound infections. The cooperation of the general practitioner must be ensured in the post-operative days. Outpatient operations lower the financial burden of the health insurance companies, medical care services can be reduced.

[Evaluation of the anesthetic risk in patients with coronary disease prior to non-cardiac surgery].

Evaluation of operative risk in coronary artery disease patients before non-cardiac surgery is a frequent problem concerning 100,000 patients each year in France. Perioperative cardiac morbidity is the first cause of death associated with non-cardiac surgery, with infarction rates of the order of 1 to 2% in coronary disease patients. These infarcts are followed by the death of the patient in 25 to 50% of cases. Evaluation of anesthetic risk is based upon three points: type of surgery, clinical findings and results of investigations. The risk is markedly increased in emergency surgery, and in thoracic, intraperitoneal and above all vascular surgery, in particular when clamping of the aorta is involved. From a clinical standpoint, only a history of infarction and signs of peripheral cardiac failure are independent predictive factors of postoperative complications. Other criteria, e.g. age, uncontrolled hypertension, diabetes and above all the severity of angina are also associated with the onset of perioperative-complications. This evaluation can be refined by electrocardiogram (Q wave, ST segment anomalies, ventricular hypertrophy and left bundle branch block) and chest X-ray. The usefulness and predictive value of exercise tests, when possible in a preoperative context, are particularly precious when the result is positive at low work-load. Many publications have studied the value of myocardial isotope scan, in particular before vascular surgery. They report the excellent negative predictive value (95 to 100%) of this investigation. Furthermore, the predictive value of isotope scan is all the greater when the clinical risk factors seen in the patients and the number of areas with ischemia are taken into account.(ABSTRACT TRUNCATED AT 250 WORDS)
