Global safe anaesthesia and surgery initiatives: implications for anaesthesia in the Pacific region.

In 2015 three major events occurred for global anaesthesia and surgery. In January, the World Bank published Disease Control Priorities 3rd edition (DCP 3rd edition). This volume, Essential Surgery, highlighted the cost effective role of anaesthesia and surgery in global health. In April, the Lancet Commission on Global Surgery released its report "Global Surgery 2030: Evidence and solutions for achieving health, welfare, and economic development". The report focuses on five key areas to promote change including: access to timely surgery, surgical workforce and procedural capability, surgical volume, data collection such as perioperative mortality rate, and financial protection. In May, the 68th World Health Assembly (WHA) voted in favour of Resolution A68/31: Strengthening emergency and essential surgical and anaesthesia care as a component of universal health coverage. The resolution was passed unanimously and it is the first time that surgery and anaesthesia have received such prominence at WHA level. These three events all have profound implications for the provision and access of safe anaesthesia and surgery in the Pacific region in the next 15 years. This article considers some of the regional factors that affect these five key areas, especially with regard to anaesthetic specialist workforce density in different parts of the region. There are many challenges to improve anaesthesia access, safety, and workforce density in the Pacific region. Future efforts, initiatives and support will help address these problems.

Delayed diagnosis of infarcted small bowel due to right-sided Bochdalek hernia.

We report a case of an adult patient with small bowel infarction, secondary to a strangulated Bochdalek hernia.

Clinical and echocardiographic diagnoses disagree in patients with unexplained hemodynamic instability after cardiac surgery.

PURPOSE: To investigate 1) if clinical indications match diagnostic findings from urgent transesophageal echocardiography (TEE) in hemodynamically unstable patients after cardiac surgery and 2) the clinical impact of the TEE findings. METHODS: Retrospective review of all postcardiac surgical intensive care patients who received an urgent TEE over a three- year period from July 1(st) 1997 until June 30(th) 2000. The clinician's presumed diagnosis based on hemodynamic and clinical evaluation was compared to TEE diagnosis. Surgical and medical interventions based on TEE results and the associated mortality were correlated. RESULTS: A hundred and thirty TEEs were performed for hemodynamic instability or suspected intracardiac vegetation or thrombus, all category I indications according to ASA guidelines. In 41.5% of patients the echocardiographic finding matched the presumed diagnosis. Patient management was significantly changed as a result of TEE findings in 58.5% of patients; 43.3% had changes in pharmacological therapy and 15.3% had a surgical intervention. Mortality was significantly lower in those who received a surgical intervention when compared to those who had changes in drug treatment (P <0.05). CONCLUSIONS: The results of urgent TEE in hemodynamically unstable patients or patients with thromboembolic phenomena in the postcardiac surgical intensive care unit are unpredictable in over half of cases. Inappropriate management decisions may result without the information obtained from TEE examination. Clinical management is often modified as a result of TEE findings. TEE is essential in the management of hemodynamically unstable postcardiac surgical patients.

Postoperative intensive care in cardiac surgery.

Postoperative intensive care in cardiac surgery is a growing area, fuelled by the increase in the number of cardiac surgical procedures performed. An increase in the number of patients has resulted in increased resource utilization. Much of the recent research in this field is concerned with the early extubation of cardiac surgical patients, reducing the length of stay in the intensive care unit and predicting which patients will have delayed extubation and a prolonged length of stay. A number of recent studies have been published advocating 'off pump' cardiac surgery as a way of reducing the physiological insult of cardiopulmonary bypass and thereby improving the postoperative course. There is still insufficient evidence that this approach reduces morbidity and intensive care unit length of stay in multi-vessel off-pump coronary artery bypass surgery. The traditional design of post-cardiac surgical intensive care units and high dependency units has also recently been challenged. More flexible integrated units improve cost control and are more suited to modern cardiac surgery.

Large bowel impaction by the BioEnterics Intragastric Balloon (BIB) necessitating surgical intervention.

A case of large bowel impaction caused by migration of a BioEnterics Intragastric Balloon (BIB) is presented. The literature is reviewed regarding both the use and the complications inherent in such balloon devices. This is the first reported case of an intragastric balloon impacted in the colon 9 months after insertion.

The value of guidelines in a breast screening service.

The use of agreed guidelines in the management of common surgical and medical conditions has received much attention and enjoys varying degrees of support. In May 1992 the UK Breast Screening Programme produced guidelines with the intention of providing criteria for all units to attempt to achieve. We have investigated these guidelines as a means of comparative audit and stimulus for change. Two units were compared, one in a teaching centre and the other in a district general hospital. Although both units performed for the most part within the guidelines, areas where improvement could be made were identified and measures to correct deficiencies taken. This resulted in improved performance in those areas. The study demonstrates that guidelines can have considerable benefit in helping to identify problems in the provision of care and introducing measures to improve the situation.

Use of a eutectic mixture of local anaesthetics in the release of preputial adhesions: is it a worthwhile alternative?

OBJECTIVE: To see if a eutectic mixture of local anaesthetics (EMLA) could be used effectively for the release of preputial adhesions as a day case procedure. PATIENTS AND METHODS: A total of 36 consecutive symptomatic children had their preputial adhesions separated under local anaesthetic with EMLA. RESULTS: The procedure was successful in 27 children. Of these, 16 remained symptom free at 9 to 12 months follow up although five children had slight recurrence of adhesions. The other 11 children were listed for circumcision at 2 weeks following the procedure because of marked recurrence of adhesions. CONCLUSION: EMLA cream is a good alternative to general anaesthetics in the separation of preputial adhesions. The technique is operator-dependent and better results were obtained when one person was using it regularly. Separation of adhesions is a worthwhile procedure in boys with symptomatic non-retractile foreskins.

GORA: a scoring system for the quantification of risk of graft occlusion.

Auditing the outcome from vascular surgery with regard to graft occlusion is made difficult by variations in the type of surgery performed and the case mix. These difficulties are compounded when attempting to compare units. In the present study we have attempted to develop a scoring system to predict the risk of graft occlusion, and thus compensate for these variables. Prospectively collected data from 214 consecutive patients undergoing vascular reconstructive surgery (233 arterial grafts) were analysed. Graft occlusion occurred in 82 patients (35.2%). Using a multivariate linear regression analysis of these data a five-factor, five-grade scoring system has been devised (GORA: Graft Occlusive Risk Assessment). Logistic regression analysis of the observed risk of occlusion with this derived score produced the following relationship between the odds ratio of occlusive risk and GORA score: (logeR/1 - R = (0.229 x score) - 4.165). The score was then validated in a different group of 186 patients (196 arterial grafts). In both groups the score was found to predict accurately the risk of graft occlusion (P < 0.001). There was no significant difference in the receiver operating characteristic curves between the estimation and validation groups.

Attenuating the hypertensive response to laryngoscopy and endotracheal intubation using awake fibreoptic intubation.

Blood pressure and pulse rate measurements were recorded in 35 patients undergoing endotracheal intubation during general anaesthesia (Group A), and 35 patients who had an awake fibreoptic intubation under local anaesthesia (Group B). The mean arterial pressure in Group A rose by a mean of 35 mmHg immediately after intubation, compared with a mean fall of 9 mmHg in Group B. The mean pulse rate in Group A rose by 24 beats per minute (b.p.m.) immediately after intubation, compared with a rise of 3 b.p.m. in Group B. Both these differences were statistically significant (P less than 0.0001 and P less than 0.001 respectively, Mann Whitney U test). Postoperative discomfort was assessed 24 h later by means of linear analogue scales. There was a statistically higher mean score in relation to nose discomfort in Group B (P less than 0.002). Awake fibreoptic intubation successfully reduces the pressor response to endotracheal intubation in normotensive adults. It is suitable for use in those patients who are at risk from the pressor response.

Horner's syndrome caused by an intercostal chest drain.

Horner's syndrome occurred in a young woman as a complication of the treatment of a traumatic pneumothorax with an intercostal drain. The nerve damage probably occurred when the lung had fully re-expanded, pressing the tip of the intercostal drain, lying at the apex of the pleural cavity, on to the sympathetic chain.

Methicillin resistant Staphylococcus aureus; the role of antisepsis in the control of an outbreak.

Between February 1983 and September 1985, an outbreak of methicillin-resistant Staphylococcus aureus involving 151 patients and staff occurred in a district general hospital. At its peak, 43 cases occurred in 3 months. Sixty-two patients suffered morbidity and two died. Conventional isolation techniques and once-daily whole body washing of affected patients with triclosan successfully controlled the outbreak.

Comparison of extraperitoneal and transperitoneal methods of aorto-iliac reconstruction. Twenty years experience.

The operative technique of extraperitoneal approach to the aorta is described. The results of operation on the aorta using this technique are compared with those using the standard transperitoneal approach.

The evaluation of cefuroxime in the prevention of postoperative infection.

Patients undergoing biliary surgery received either 750 mg cefuroxime i.m. with the premedication and then 8 hourly for 3 days ((group A) or 1.5 g cefuroxime i.v. at the time of induction of anaesthesia (group B) or not treatment (group C). Wound infections occurred in 3 out of 35 patients in group A, 1 out of 40 patients in group B and 11 out of 39 patients in group C (group B significantly different than group C, P less than 0.05). Eight patients (23%) in group C had chest complications. Cefuroxime was effective in the reduction of wound sepsis following biliary surgery and 1.5 g i.v. administered during induction of anaesthesia is the dosage of choice. The incidence of chest infection tended to be lower in patients receiving cefuroxime but many more patients would have to be studied for a conclusive result.
