    Notes: A comparison was made of the drug costs and nursing dependency of patients undergoing elective cardiac surgery and routine postoperative recovery for two anaesthetic techniques using either propofol with low dose fentanyl or midazolam with high dose fentanyl. Estimates of resource use were based on a randomised clinical trial undertaken at the Northern General Hospital, Sheffield. Times from entry to the intensive care unit until extubation and discharge were recorded for 70 patients and were transformed to nursing shifts. Nursing dependency was calculated on the basis of one nurse per ventilated patient and 0.5 nurse from the start of the shift after extubation. Nursing costs were allocated on the basis of the patient's status at the beginning of each shift in line with the hospital's staffing policy. All drugs used from the morning of the operation until discharge were recorded. Costs of nursing and drugs were calculated. The total cost of patients in the propofol group was 13.3% less than midazolam patients (p = 0.043, for geometric means Cl 0.4% to 27.8%). The clinical study was not designed for economic endpoints; however, it demonstrated achievable savings in propofol-treated patients.

    Notes: This study was designed to compare the cardiorespiratory effects of high frequency jet ventilation at 150 breaths/minute with and without added positive end expiratory pressure, with conventional intermittent positive pressure ventilation in 20 patients following aortocoronary bypass graft surgery. On comparison with intermittent positive pressure ventilation, there was a decrease in peak airway pressure during high frequency jet ventilation when positive end expiratory pressure of 0 or 0.5 k Pa was applied, but not with 1 k Pa. and an increase in mean airway pressure with positive end expiratory pressures of 0.5 and 1 k Pa. On changing from intermittent positive pressure to high frequency jet ventilation with no added end expiratory pressure, there was an acute decrease in arterial oxygen tension and increases in cardiac output and total tissue oxygen delivery. On changing from intermittent positive pressure ventilation to high frequency jet ventilation with I k Pa of positive end expiratory pressure, there was an acute decrease in arterial oxygen tension, cardiac output and oxygen delivery, and increases in pulmonary arterial, right atrial and pulmonary capillary wedge pressures. The addition of positive end expiratory pressure did not prevent the acute decrease in arterial oxygen tension which occurred on transfer to high frequency jet ventilation.

    Notes: A patient who presented with nasal obstruction 4 months after prolonged pernasal tracheal intubation is described. The cause of the obstruction was an adhesion which extended from the septum to the inferior turbinate. The evidence in support of long-term pernasal tracheal intubation is presented and the aetiology of this complication is discussed.

    Notes: The cardiorespiratory effects of intermittent positive pressure ventilation and high frequency jet ventilation with and without positive end expiratory pressure were compared in patients following valvular heart surgery (mitral and/or aortic). Twenty patients received intermittent positive pressure ventilation and high frequency jet ventilation with 0. 0.5 and 1.0 kPa positive end expiratory pressure. High frequency jet ventilation was well tolerated. The addition of 1.0 kPa positive end expiratory pressure was associated with preservation of the arterial oxygen tension without any increase in shunt or significant adverse haemodynamic effect. The results are discussed and compared with a previous study of high frequency jet ventilation following aortocoronary bypass graft surgery.

    Notes: The case histories of two patients who required the insertion of intratracheal stents are presented. The peroperative anaesthetic management of one case included the use of high frequency jet ventilation of the lungs; in the other case, partial cardiopulmonary bypass was used. The advantages and disadvantages of these two methods are discussed.

    Notes: The problems encountered in the immediate postoperative period in an undiagnosed myxoedematous patient are reported, the specific management of these problems discussed and the treatment of myxoedema coma outlined. The use of dopamine for cardiovascular support in this situation is commented upon.

    Notes: This study examined the effectiveness of a new type of chest drain, which incorporates an additional lumen within its wall to facilitate the administration of intrapleural bupivacaine. Nine patients who received a bolus dose of 1.5 mg.kg−1 bupivacaine with 1:200 000 adrenaline through this chest drain used less morphine, and had lower visual analogue pain scores in the first 6 h after thoracotomy than patients in whom a standard chest drain had been used. Bupivacaine levels were found to be within safe limits in all patients.

    Notes: We describe the use of a milrinone infusion as a bridge to heart transplantation in the treatment of severe congestive cardiac failure secondary to viral cardiomyopathy. The clinical improvement that occurred when milrinone was commenced made it possible to wean the patient from conventional cardiovascular support with an intra-aortic balloon pump and dobutamine. There was an improvement in organ perfusion.

    Notes: The aim of this randomised controlled study was to determine whether an esmolol infusion affected the incidence of ST segment changes during weaning from intermittent positive pressure ventilation and tracheal extubation after coronary artery surgery. Thirty-one patients received an infusion of esmolol 0–300 µg.kg−1.min−1 and 37 patients comprised the control group. ST segment changes were monitored using a continuous ambulatory surveillance system. The electrocardiogram, direct arterial pressure and pulse oximetry were monitored continuously. The period of analysis was from 120 min before until 180 min after tracheal extubation. Three patients in the esmolol group developed myocardial ischaemia during the study period compared with 12 in the control group (p = 0.05). Heart rate increased with time during the study period (p = 0.002) in the control group but was unchanged in the esmolol group. Mean heart rate was significantly higher in the control group than in the esmolol group from 40 min before until 180 min after tracheal extubation. Seven patients in the esmolol group suffered adverse events related to the esmolol infusion. Although the use of esmolol reduced the incidence of myocardial ischaemia, the incidence of adverse effects makes it unsuitable prophylaxis for patients after coronary artery surgery.

    Notes: Total intravenous anaesthesia with propofol and fentanyl was used in 23 patients undergoing coronary artery and 16 patients undergoing valve surgery and the haemodynamic effects in the two groups were compared. Baseline values showed that the valve surgery group had a higher mean heart rate, pulmonary artery wedge pressure and pulmonary artery pressure and smaller mean stroke volume than the coronary artery surgery group. In both groups, heart rate, arterial pressure, pulmonary artery wedge pressure, pulmonary artery pressure and cardiac index decreased during surgery. In the valve surgery group there were greater percentage decreases in heart rate, mean arterial pressure and diastolic arterial pressure. Overall, propofol and moderate-dose fentanyl anaesthesia was no more detrimental to the haemodynamics in patients undergoing valve surgery when compared to those undergoing coronary artery surgery.
