The use of a World Health Organization Transfusion Basic Information Sheet to evaluate transfusion practice in Croatia.

BACKGROUND AND OBJECTIVES: To assess the feasibility of using the World Health Organization (WHO) Transfusion Basic Information Sheet as a bedside tool for data collection and assessing transfusion practice. MATERIALS AND METHODS: A prospective 6-month audit of all transfusion episodes using the tool. RESULTS: Eight hundred and twenty-two forms were completed, capturing data on 59.7% of transfusion episodes. Completion of data fields was > 80%, except for the clinician's transfusion targets that were documented in only 58.5% of cases. Twenty per cent of patients received single red cell unit transfusions. CONCLUSIONS: The Basic Information Sheet can be incorporated into bedside clinical practice. We have identified the need to encourage clinicians to determine and document their transfusion targets before prescribing blood components.

Bronchopulmonary sequestration and dextrocardia.

Bronchopulmonary sequestration (BPS) is usually a rare congenital anomaly, which is most frequently extralobar or intralobar. The case of a patient with positional congenital anomaly--dextrocardia (situs thoracalis inversus) and intrapulmonary sequestration (IPS) is presented. Clinical and radiological characteristics of EPS and IPS are discussed, and new combinations of congenital anomalies with bronchopulmonary sequestration are described, dextrocardia and intrapulmonary sequestration. The importance of the algorithm of diagnostic examinations is emphasized, from detection of bronchopulmonary sequestration on the chest roentgenogram to establishing a definite diagnosis by means of angiography.

Effect of neuroleptanaesthesia on VA/Q distribution and pulmonary shunt.

The authors studied changes in the ventilation-perfusion ratio and pulmonary shunt in the course of pulmonary surgery in relation to their presurgery values. The study was conducted at the Jordanovac University Department for Thoracal Surgery in Zagreb, examining 35 patients in whom, owing to pulmonary carcinoma, thoracotomy and pulmonary resection were performed. Relevant data were obtained concerning hypoxemia, its incidence, and its intensity in the patients examined. The results obtained have shown that in the presurgery period all the patients had an elevation of pulmonary shunt and an increased ratio of ventilation and blood flow, leading to mild hypoxemia. During the operation, the fall of the pulmonary shunt amounted to 8%; it was smaller after the ligature (bronchi, artery, and vein of the respective lung or its part) than at the end of the surgery (P < 0.001), whereas the ventilation-perfusion ratio fell more markedly after ligature (P < 0.001) than at the end of the operation. The authors conclude that, by knowing the ventilation-perfusion ratio and pulmonary shunt in the presurgical period, it is not possible to predict the changes of these parameters in the course of surgery. This is of special importance, because hypoxemia, occurring as a result of changes in the ventilation-perfusion ratio and pulmonary shunt, seriously endangers the patient's fate during surgery.

[Correlation analysis of pulmonary shunt after resection the lung].

Thirty-three patients with performed thoracotomy and lung resection were studied by measuring changes in shunting after they had undergone the breathing of 100% O2 for 20 minutes during the operative procedure and the immediate postoperative period. The obtained values of the shunt were compared with those in the preoperative period by making a correlative analysis, with a view to examining whether the shunt values and hypoxemia during the operation and the postoperative period could be foreseen on the basis of data on the preoperative shunt. The shunt was calculated from the following equation: Qs/Qt = CcO2--CaO2/CaO2--CvO2.

[Comparison between the rubber Carlens tube and the polyvinylchloride Robertshaw tube for endobronchial intubation].

The aims of the study were to compare prospectively two double-lumen endobronchial tubes (DLTs): red rubber Carlens and left polyvinylchloride Robertshaw DLT with regard to difficulties in intubation and complications during one-lung ventilation. Sixty-two adult patients were randomly intubated with Carlens tube (31 patients) or Robertshaw tube (31 patients). Correct placement of DLTs was assessed using clinical signs and in some patients in the Robertshaw group fiberoptic bronchoscope was used. In the group intubated with the Carlens tube there were significantly more difficulties in passing the tube through the larynx (4 out of 31 patients), compared with the Robertshaw group (not a single patient). There was no difference in the number of patients with difficulties in placing the tube in the left main bronchus; however, the nature of the problem was more complex with the Carlens tube. The frequency of all the complications as well as the occurrence of the most common complications--hypoxemia and increased peak airway pressure, was not different between the groups. In both groups hypoxemia was related to the right side of the operation. Fiberoptic bronchoscope was used in 18 out of 31 patients intubated with the Robertshaw tube. Its use was not correlated with decreased incidence of complications compared to intubation in which tube position was assessed by clinical signs only.

[Approach to artificial respiration using differential ventilation in open thoracic surgery].

The purpose of our study was to correct the vertical ventilation perfusion anomaly in lateral position using a differential ventilation with the two identical electronic synchronized "Servo" ventilators, during the thoracotomy. Our study included 44 patients. The differential ventilation has been investigated on the two clinically standardized simplified models. In model 1 distribution of the ventilation volume dependent-independent lung was 50%/50% with a selective PEEP in the dependent lung of 10 cm/H2O. In model 2 distribution of ventilation volume dependent-independent lung of 70%/30% with selective PEEP in the dependent lung of 5 cm H2O. Statistical analysis of our results shows that if we use the differential ventilation model 2 during the thoracotomy we could obtain: a) the lowest values of the shunt in the group of pulmonary patients b) elimination of an appearance of a single critical values of the shunt and a low value of PaO2 in both groups of patients.
