Age and the anaesthetist: considerations for the individual anaesthetist and workforce planning: Guidelines about the ageing anaesthetic workforce from the Association of Anaesthetists: Guidelines for the ageing anaesthetic workforce from the Association of Anaesthetists

There is clear evidence of a growing workforce gap and this is compounded by demographic data that show the current workforce is ageing. Within the current workforce, more doctors are taking voluntary early retirement and the loss of these experienced clinicians from departments can have wide-ranging effects. Older doctors are at risk of age-related health problems (e.g. sight, musculoskeletal, menopause) and are more susceptible to the effects of fatigue, which may increase the risk of error and or complaint. The purpose of this working party and advocacy campaign was to address concerns over the number of consultants retiring at the earliest opportunity and whether a different approach could extend the working career of consultant anaesthetists and SAS doctors. This could be viewed as 'pacing your career'. The earlier this is considered in a clinician's career the greater the potential mitigation on individuals.

Substance use disorder in the anaesthetist: Guidelines from the Association of Anaesthetists: Guidelines from the Association of Anaesthetists

Anaesthetists have a higher incidence of substance use disorder when compared with other doctors. This might be due to the ease of access to intravenous opioids, propofol, midazolam, inhalational agents and other anaesthetic drugs. Alcohol use disorder continues to be the most common problem. Unfortunately, the first sign that something is amiss might be the anaesthetist's death from an accidental or deliberate overdose. While there are few accurate data, suicide is presumed to be the cause of death in approximately 6-10% of all anaesthetists. If we are to prevent this, substance use disorder must be recognised early, we should ensure the anaesthetist is supported by their department and hospital management and that the anaesthetist engages fully with treatment. Over 75% of anaesthetists return to full practice if they co-operate fully with the required treatment and supervision.

A national survey of out-of-hours working and fatigue in consultants in anaesthesia and paediatric intensive care in the UK and Ireland

The tragic death of an anaesthetic trainee driving home after a series of night shifts prompted a national survey of fatigue in trainee anaesthetists. This indicated that fatigue was widespread, with significant impact on trainees' health and well-being. Consultants deliver an increasing proportion of patient care resulting in long periods of continuous daytime duty and overnight on-call work, so we wished to investigate their experience of out-of-hours working and the causes and impact of work-related fatigue. We conducted a national survey of consultant anaesthetists and paediatric intensivists in the UK and Ireland between 25 June and 6 August 2018. The response rate was 46% (94% of hospitals were represented): 84% of respondents (95%CI 83.1-84.9%) contribute to a night on-call rota with 32% (30.9-33.1%) working 1:8 or more frequently. Sleep disturbance on-call is common: 47% (45.6-48.4%) typically receive two to three phone calls overnight, and 48% (46.6-49.4%) take 30 min or more to fall back to sleep. Only 15% (14.0-16.0%) reported always achieving 11 h of rest between their on-call and their next clinical duty, as stipulated by the European Working Time Directive. Moreover, 24% (22.8-25.2%) stated that there is no departmental arrangement for covering scheduled clinical duties following a night on-call if they have been in the hospital overnight. Overall, 91% (90.3-91.7%) reported work-related fatigue with over half reporting a moderate or significantly negative impact on health, well-being and home life. We discuss potential explanations for these results and ways to mitigate the effects of fatigue among consultants.

A national survey of the effects of fatigue on trainees in anaesthesia in the UK

Long daytime and overnight shifts remain a major feature of working life for trainees in anaesthesia. Over the past 10 years, there has been an increase in awareness and understanding of the potential effects of fatigue on both the doctor and the patient. The Working Time Regulations (1998) implemented the European Working Time Directive into UK law, and in August 2009 it was applied to junior doctors, reducing the maximum hours worked from an average of 56 per week to 48. Despite this, there is evidence that problems with inadequate rest and fatigue persist. There is no official guidance regarding provision of a minimum standard of rest facilities for doctors in the National Health Service, and the way in which rest is achieved by trainee anaesthetists during their on-call shift depends on rota staffing and workload. We conducted a national survey to assess the incidence and effects of fatigue among the 3772 anaesthetists in training within the UK. We achieved a response rate of 59% (2231/3772 responses), with data from 100% of NHS trusts. Fatigue remains prevalent among junior anaesthetists, with reports that it has effects on physical health (73.6% [95%CI 71.8-75.5]), psychological wellbeing (71.2% [69.2-73.1]) and personal relationships (67.9% [65.9-70.0]). The most problematic factor remains night shift work, with many respondents commenting on the absence of breaks, inadequate rest facilities and 57.0% (55.0-59.1) stating they had experienced an accident or near-miss when travelling home from night shifts. We discuss potential explanations for the results, and present a plan to address the issues raised by this survey, aiming to change the culture around fatigue for the better.

Counting the cost of surgical training: perspective from a school of surgery

It has long been acknowledged that hospital doctors train their juniors with only limited extra time or support and little formal training for their role. The introduction of job planning was intended to recognise formally the additional time needed for this and other activities and the new Postgraduate Medical Education and Training Board (PMETB) standards for trainers are intended to address the need for faculty development. If these Standards for trainers are to be achieved, regulators may need to provide clearer guidance to trusts about the time required in job plans to deliver the expected standard of educational and clinical supervision and other deanery and royal college educational roles.

Why do women reject surgical careers?

The objective of this study was to identify some of the reasons why women reject surgical careers, and to suggest actions which might reverse that trend. The subjects were new entrants to medical school, third-year medical students and pre-registration house officers (PRHOs) at the Medical School of Newcastle-upon-Tyne.

METHOD

A cross-sectional descriptive survey, using a self-administered questionnaire.

RESULTS

Of 247 females surveyed, 99 (40%) had rejected surgical careers, mainly because of 'personal preference'. Women saw such careers as unfavourable to them, largely because of a perception of male bias. No more than 10% of females in each subject group had surgical role-models. The perceived quality of teaching and friendliness of consultants had a significant influence on career decisions.

CONCLUSIONS

Women reject surgical careers because of perceptions of 'male bias' and 'negative attitudes'. An increase in the number of surgical role models among women could improve this situation, as could apparent enthusiasm for teaching and enjoyment of their specialty by consultants.

Developing senior doctors as mentors: a form of continuing professional development. Report Of an initiative to develop a network of senior doctors as mentors: 1994-99

BACKGROUND

Senior doctors report that mentoring skills are transferable to everyday medical practice and managing juniors. An analysis of views from consultants and general practitioners, who had trained together on a regional mentoring scheme, reveals significant potential for personal and professional development in such networks.

CONTEXT

The Northern and Yorkshire Region Doctors' Development and Mentoring Network was set up in 1994. Since then there have been six programmes with 116 senior doctors participating. In 1997 there was an evaluation of the first four programmes.

METHOD

Focus groups and postal questionnaire.

RESULTS

There were responses from 71 senior doctors, giving a response rate of 86%, and responses from 78 professional stakeholders in 49 NHS organizations, a response rate of 54%. Results indicate that the programmes were highly valued by the participants, particularly with regard to: being part of a network of senior doctors; developing mentoring skills, and engaging in personal and professional development. The most difficult part of the programme was setting up mentoring networks for junior doctors, and reasons included: personal factors, such as levels of confidence in providing mentoring; cultural factors, such as juniors not wishing to be seen to need help, and organizational factors, such as lack of time allocated for mentoring. RECOMMENDATIONS AND ISSUES FOR FURTHER DEBATE: The positive benefits from the scheme raise questions about how to develop mentoring training for senior doctors. Issues include: developing mentors; who needs mentoring; mentoring and the organization; transferability of mentoring skills, and widening the network.

A study of junior doctors to investigate the factors that influence career decisions

Both pre-registration house officers and general practitioner (GP) registrars agree on several desirable and undesirable factors that define their ideal career. These relate to fulfilling clinical work and preservation of a meaningful personal life. Many young doctors regret their choice of medicine as a career because of poor job conditions and stress and perceive career advice as inadequate. GP's influence over junior doctors at the time of their career decision making is very limited compared with that of consultants.

Anaesthetic management of Caesarean section in an elderly parturient with pre-eclampsia

The number of women over 40 years of age becoming pregnant has increased over recent years. They suffer a high incidence of hypertensive complications, and require more frequent operative interventions. We present a case report of a 51-year-old woman having a Caesarean section for a twin pregnancy complicated by pre-eclampsia. We discuss the effects of age on pregnancy and the implications for anaesthetic management.

Exaggerated cardiovascular response to anaesthesia--a case for investigation

We present a case of a 40-year-old woman who developed major cardiovascular complications during anaesthesia for an elective clipping of a cerebral arteriovenous malformation. Postoperative investigation confirmed the diagnosis of an adrenal phaeochromocytoma. In retrospect, it became apparent that she had experienced a series of potentially life-threatening events over a 20-year period all of which are known complications of phaeochromocytoma. This case highlights the importance of investigating young patients who have unexpected and unexplained cardiovascular events during anaesthesia and surgery.

Low-dose clonidine infusion during labour

In this study, we have compared two different doses of clonidine (bolus of 25 micrograms and infusion of 19 micrograms h-1; bolus of 50 micrograms and infusion of 37 micrograms h-1, both added to 0.03% bupivacaine) with a control group of 0.03% bupivacaine alone. The study was performed in a randomized, double-blind manner, and a total of 45 patients were studied. Both clonidine regimens resulted in marked local anaesthetic sparing, with no change in the quality of analgesia. There was no difference in the severity of lower limb motor weakness and no difference in maternal sedation, although only a small number of patients were studied. No adverse maternal haemodynamic effects were observed. The newborn infants were not sedated on delivery. The number of fetal cardiotocographic traces judged to be of concern was higher in both clonidine groups. However, this just failed to reach statistical significance (P = 0.055).

Randomized trial of bolus phenylephrine or ephedrine for maintenance of arterial pressure during spinal anaesthesia for Caesarean section

Thirty-eight healthy women undergoing elective Caesarean section under spinal anaesthesia at term were allocated randomly to receive boluses of either phenylephrine 100 micrograms or ephedrine 5 mg for maintenance of maternal arterial pressure. The indication for administration of vasopressor was a reduction in systolic pressure to < or = 90% of baseline values. Maternal arterial pressure (BP) and heart rate (HR) were measured every minute by automated oscillometry. Cardiac output (CO) was measured by cross-sectional and Doppler echocardiography before and after preloading with 1500 ml Ringer lactate solution and then every 2 min after administration of bupivacaine. Umbilical artery pulsatility index (PI) was measured using Doppler before and after spinal anaesthesia. The median (range) number of boluses of phenylephrine and ephedrine was similar; 6 (1-10) vs 4 (1-8) respectively. Maternal systolic BP and CO changes were similar in both groups, but the mean [95% CI] maximum percentage change in maternal HR was larger in the phenylephrine group (-28.5 [-24.2, -32.9]%) than in the ephedrine group (-14.4 [-10.6, -18.2]%). As a consequence atropine was required in 11/19 women in the phenylephrine group compared with 2/19 in the ephedrine group (P < 0.01). Mean umbilical artery pH [95% CI] was higher in the phenylephrine group (7.29 [7.28-7.30]) than in the ephedrine group (7.27 [7.25-7.28]). The results of the present study support the use of phenylephrine for maintenance of maternal arterial pressure during spinal anaesthesia for elective Caesarean section.

Women's experiences of repetitively contracting sexually transmitted diseases

Our purpose in conducting this qualitative, descriptive research was to explore and describe women's experiences of repetitively contracting sexually transmitted diseases (STDs). Ten open-ended, semistructured, in-depth interviews with 8 women, along with stories and anecdotes from one author's clinical practice, provided data. Thematic analysis was used to generate themes important to the women. Themes included the power and significance of heterosexual relationships, female powerlessness, the sense that STDs are an inevitable part of a woman's life, stigma, and victimization. The women's explanatory models for the STDs were quite different from those of health care providers evidenced in the professional literature. The findings from this research support the following suggestions for practice: (a) Practitioners and clients should share their explanatory models to work toward safe sexual behavior, and (b) practitioners need to scrutinize their practices to make sure they are not minimizing the risks of STDs.

Hydralazine boluses for the treatment of severe hypertension in pre-eclampsia

OBJECTIVE

To audit the use of bolus hydralazine for control of severe hypertension within a protocol for the management of severe pre-eclampsia.

DESIGN

A retrospective review.

SETTING

Three UK teaching hospitals.

SUBJECTS

Seventy consecutive women who received hydralazine for the treatment of sustained severe hypertension. Twenty-five women had more than one episode of hypertension amounting to a total of 109 treatment episodes.

INTERVENTION

Intravenous bolus hydralazine 5 mg, repeated every 15 min to reduce the mean arterial pressure to < 125 mmHg.

MAIN OUTCOME MEASURES

Change in mean arterial pressure in response to bolus hydralazine, fetal condition, as assessed by heart rate changes and umbilical arterial pH at delivery, and protocol violations were analysed.

RESULTS

Mean arterial pressure fell by 12 mmHg (95% CI 10-14) after the first bolus, 9 mmHg (95% CI 6.5-12) after the second bolus and 5 mmHg (95% CI 1-10) after the third bolus. Eighty-two (75%) episodes were managed strictly according to the protocol; of these, blood pressure was controlled by bolus therapy alone in 89%. Of the 27 instances in which the protocol was not adhered to, blood pressure was not controlled in four. There were no significant differences in the incidence of cardiotocographic abnormalities or umbilical acidaemia in the women treated before delivery (n = 36) compared with those in whom treatment was first initiated afterwards (n = 34).

CONCLUSIONS

Hydralazine given in 5 mg boluses is a safe and effective method of treating severe hypertension in pre-eclampsia. Despite clear management guidelines, protocol violations were common, and in 4% of treatment episodes these were potentially serious resulting in failure to control blood pressure.

Influence of droperidol on nausea and vomiting during patient-controlled analgesia

We have studied the addition of droperidol to morphine during patient-controlled analgesia (PCA) in 57 patients using PCA after abdominal hysterectomy. Patients in group 1 (control group) received placebo at induction of anaesthesia and a PCA containing morphine; those in group 2 received droperidol 1.25 mg and a PCA containing morphine and those in group 3 droperidol and a PCA containing droperidol 0.05 mg mg-1 of morphine. Patients in the control group suffered 51 episodes of nausea compared with 35 in the droperidol bolus group and 18 in the droperidol PCA group (P < 0.01). In the droperidol PCA group, only 10 doses of additional antiemetic therapy were required compared with 24 in the droperidol bolus group and 28 in the control group (P < 0.05). We did not observe side effects attributable to droperidol. We conclude that droperidol added to morphine in PCA reduces nausea and antiemetic requirements after abdominal hysterectomy.

Phenytoin prophylaxis in severe pre-eclampsia and eclampsia

OBJECTIVE

To determine plasma phenytoin levels and seizure outcome in women given phenytoin for seizure prophylaxis in severe pre-eclampsia and eclampsia.

DESIGN

Prospective observational study comparing two phenytoin loading regimens.

SETTING

Two UK teaching hospitals.

SUBJECTS

Sixty-seven consecutive women with severe pre-eclampsia and five with eclampsia.

INTERVENTIONS

The first 29 women were given a 15 mg/kg intravenous loading dose of phenytoin. The next 43 received 17.5 mg/kg. All were given 500 mg phenytoin 12 h after completion of the loading dose and then 250 mg every 12 h for four doses.

MAIN OUTCOME MEASURES

Total plasma phenytoin levels at 30 min, 6 h and 12 h after loading dose, 6 h after first maintenance dose and on days 2 and 3 of maintenance therapy; eclamptic seizures after starting phenytoin.

RESULTS

Mean plasma phenytoin levels were higher at 30 min and 6 h after the 17.5 mg/kg loading dose. Nine of 29 (31%) phenytoin levels 30 min after the loading dose were above the therapeutic range in the 15 mg/kg group compared with 26/38 (68%) in the 17.5 mg/kg group (P < 0.01). Six of 27 (22%) phenytoin levels 12 h after the loading dose were subtherapeutic in the 15 mg/kg group compared with 2/38 (5%) in the 17.5 mg/kg group (P < 0.05). Three women, two in the 17.5 mg/kg group, developed seizures after starting phenytoin. All three had plasma levels within the therapeutic range.

CONCLUSIONS

Compared with a loading dose of 17.5 mg/kg, loading with 15 mg/kg phenytoin was associated with a lower incidence of high plasma levels at 30 min but a higher incidence of subtherapeutic levels at 12 h. Seizures occur in 2 to 3% of pre-eclamptics despite apparently therapeutic phenytoin levels.

Morbidity among anaesthetists

Anaesthetists may be exposed to a number of occupational hazards. These include exposure to infections, environmental pollution with volatile anaesthetic agents and psychological and stress-related illness which may predispose to drug dependence or suicide.

Obstetric anaesthesia in dystrophia myotonica

Two patients with dystrophia myotonica presented for urgent Caesarean section. Their per- and postoperative courses illustrate the anaesthetic problems posed by this disease. Respiratory difficulties are compounded by pregnancy and there is increased susceptibility to uterine haemorrhage. Choice of anaesthetic agent is discussed. Both had general anaesthetics; muscle relaxation was achieved with vecuronium.

The management of caesarean section in a patient with an intracranial arteriovenous malformation

The anaesthetic management of elective Caesarean section in a 25-year-old woman with an inoperable intracranial arteriovenous malformation is described. The literature is reviewed.

Anaesthesia for trans-sternal thymectomy in myasthenia gravis

A retrospective review is presented of the thirty patients who underwent trans-sternal thymectomy for myasthenia gravis in our unit from 1980-85. The clinical status of these patients is contrasted to that of more severely debilitated patients described by other authors. The problems encountered by the anaesthetist in the perioperative care of patients with mild myasthenia gravis are discussed. Management of the perioperative anticholinesterase regime is described and a case presented for the use of suxamethonium for intubation. A less invasive postoperative regime is advocated in which tracheostomy and nasotracheal intubation are avoided, and anticholinesterase therapy is re-introduced orally as soon as possible after surgery.

Alfentanil for caesarean section complicated by severe aortic stenosis. A case report

Alfentanil 35 micrograms kg-1, was used successfully in a patient with severe aortic stenosis, in order to minimize the haemodynamic responses to intubation and surgery during Caesarean section. The baby was delivered apnoeic, unresponsive and with poor muscle tone, but responded rapidly to naloxone. Plasma alfentanil concentrations and percentage binding to plasma proteins were measured in both maternal and neonatal blood. Free drug concentrations were similar in both mother and neonate, but maternal plasma proteins had a higher affinity for alfentanil. Only 67.26% of neonatal plasma alfentanil was bound to plasma protein. This value did not differ significantly from those estimated from the blood of a further 12 healthy neonates.

Blood glucose in anaesthetised children. Comparison of blood glucose concentrations in children fasted for morning and afternoon surgery

Blood glucose levels were measured immediately after induction of anaesthesia and again intraoperatively in 26 children fasted overnight for operations in the morning and 28 children fasted from 8.00 a.m. for afternoon surgery. The mean post-induction glucose concentration of the afternoon surgery group was significantly lower than that of the morning group. However, no child in either group was hypoglycaemic. Anesthesia and surgery caused significant increases in blood glucose levels. It is concluded that pre-operative fasting is well tolerated in healthy pre-school children, regardless of the timing of surgery.

Incremental propofol for short procedures

Propofol was used to induce and maintain anaesthesia in patients undergoing minor gynaecological procedures. Quality of anaesthesia, the rate of recovery and the influence of different methods of premedication were assessed. Unpremedicated patients required a higher induction dose than those premedicated with either lorazepam or papaveretum and hyoscine, but maintenance dose requirements were comparable. Regardless of premedication, there were similar decreases in mean arterial pressure, although respiratory function recovered more rapidly in patients premedicated with lorazepam. No significant changes in heart rate were noted in any group. The overall incidence of pain on injection was 3.7% (lignocaine 0.5 mg added to each 9.5 mg of propofol) and a skin rash occurred in 6% of patients. All patients recovered rapidly and uneventfully.
