    Notes: The utilisation of the pre-operative ECG in patients undergoing routine surgery was investigated in 354 adult patients over a 2-week period. Sixty-four percent of patients had an ECG pre-operatively. An ECG was not performed in 17% of patients who, current hospital policy suggests, should have had one. In contrast, an ECG was performed in 33% of patients who, hospital policy suggests, have no need of one (all of which were normal), which represented 18% of the total number of pre-operative ECGs performed. In 62% of patients with known cardiac disease, and 44% of patients with strong risk factors for ischaemic heart disease (in the absence of known disease) the ECG was abnormal. This compares with only 7% of patients aged over 50 with no risk factors in whom the ECG was abnormal. These findings suggest that there is room for improvement in the utilisation of the pre-operative ECG, which may have cost implications.

    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.

    The response times during anaesthesia of pulse oximeters measuring oxygen saturations during hypoxaemic events (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 47 (1992), S. 0 
    Details

    Topics: Medicine
    Notes: Episodes of desaturation were recorded simultaneously by computer from two Ohmeda Biox 3700 pulse oximeters, one with an ear and one with a finger probe, on patients undergoing anaesthesia. Over a period of 6 months, 28 episodes of desaturation were detected. Analysis of the recordings showed the mean minimum saturations recorded for ear and finger probes were 86.3% and 83.5% respectively (p 〈 0.01). The mean delay for finger compared to ear pulse oximetry was 4.4 s (p 〈 0.01). Analysis at different saturation levels showed finger probe responses to be significantly slower than ear probe responses at saturations equal to and above 91% (p 〈 0.05). At saturation levels of 90% or less no significant difference in probe response times were found.

    Notes: A postal survey was conducted to gain information on the use of policies on oral intake, selection of mothers and type of intake given during established labour by all maternity units in England and Wales. A response rate of 91.6% (351 out of 383) was achieved; 79.5% of units had a written policy for oral intake, 96.4% of units allowed mothers some form of oral intake and 68.3% of these units selected mothers according to risk categories. Of the 268 units allowing oral intake, 67.2% gave drink only and 32.8% drink and food. Of those allowing food, all but 13.6% had a selection policy. Of the 85 units not selecting mothers, 78.8% gave water only; the remaining 21.2% gave water and other drink or food. This survey demonstrates a wide variation in policies for oral intake during labour.

    Drug absorption after general anasthesia for minor surgery (1984)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Paracetamol absorption after oral adminstration was studied in eleven patients immediately after a short general anasthetic for cystoscopy and also in eight healthy volunteers. There were no statistical differences between the rate of paracetamol absorption in the two groups. This suggests that oral medication may be given immediately following a short general anasthetic when opioid drugs are avoided.

    An evaluation of the effect of vasodilatation on oxygen saturations measured by pulse oximetry and venous blood gas analysis (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Anaesthesia 48 (1993), S. 0 
    Details
    ISSN: 1365-2044
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Measurements of arterial oxygen saturation were estimated using a pulse oximeter under conditions of reactive hyperaemia in the arms of 10 volunteers. Oxygen saturation measured by pulse oximetry was significantly lower, and venous oxygen saturation measured by co-oximetry was significantly higher, in the hyperaemic arm than in the other arm. Pulse oximeters analyse the pulsatile component of blood flow and exclude nonpulsatile causes of absorption in estimating arterial oxygen saturation. The pulsatile component is assumed to be purely of arterial origin. However, other vessels may pulsate when vasodilatation occurs and pulse oximeter saturation readings taken under these conditions may not give a true reflection of arterial saturation.

    Anaesthetists' attitudes to parental presence at induction of general anaesthesia in children (1993)

    Notes: Attitudes of anaesthetists of various grades working in different types of hospital in England and Wales, to parental presence in the anaesthetic room during induction of anaesthesia in children were assessed by means of a postal questionnaire. Of the 300 questionnaires sent out, 244 (82%) were completed. The majority of anaesthetists were in favour of parental presence in the anaesthetic room for induction of anaesthesia in children over the age of 1 year undergoing routine day case surgery. A small but significant number expressed reservations about some aspects of parental presence. The grade of anaesthetist and type of hospital did not appear to influence the response.

    Lignocaine spray applicators are a potential source of cross-infection in the anaesthetic room (1993)

    Notes: Ten percent lignocaine spray is in widespread clinical use as a means of suppressing responses to tracheal intubation, ft is sprayed from a multidose container into the glottis and on to the vocal cords through an applicator nozzle, which may be used on successive patients. We have investigated the likelihood of the contamination of these nozzles, with patients' mouth flora. Spray applicators from four of the 20 cases investigated showed contamination with potential bacterial pathogens. We therefore recommend that lignocaine spray should not be applied to successive patients using the same applicator nozzle.

    Intra-operative pulmonary embolism Detection by pulse oximetry (1990)

    Notes: A case is presented of a 49-year-old patient who had a pulmonary embolism during ovarian cystectomy. The only evidence of its occurrence was a sudden, marked reduction in arterial oxygen saturation as detected by a pulse oximeter. The diagnosis was confirmed 24 hours later by a chest radiograph and a ventilation perfusion scan. Anticoagulant treatment was instituted.

    Evaluation of the predictive performance of a ‘Diprifusor’ TCI system[‘Diprifuso] (1998)

    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: The predictive performance of a ‘Diprifusor’ target controlled infusion system for propofol was examined in 46 patients undergoing major surgery, divided into three age groups (18–40, 41–55 and 56–80 years). Measured arterial propofol concentrations were compared with values calculated (predicted) by the target controlled infusion system. Performance indices (median performance error and median absolute performance error) were similar in the three age groups, with study medians of 16.2% and 24.1%, respectively. Mean values for ‘divergence’ and ‘wobble’ were −7.6%.h−1 and 21.9%, respectively. Measured concentrations tended to be higher than calculated concentrations, particularly following induction or an increase in target concentration. The mean (SD) propofol target concentration of 3.5 (0.7) μgml−1 during maintenance was lower in older patients, compared with higher target concentrations of 4.2 (0.6) and 4.3 (0.7) μgml−1 in the two younger age groups, respectively. The control of depth of anaesthesia was good in all patients and the predictive performance of the ‘Diprifusor’ target controlled infusion system was considered acceptable for clinical purposes.
