One- and two-year outcomes and predictors of mortality following emergency laparotomy: a consecutive series from a United Kingdom teaching hospital.

BACKGROUND: Data on outcomes of patients who underwent emergency laparotomy (EML) are limited. This prospective observational study examined aspects of inpatient care and outcomes following EML with a view to identifying predictors of mortality. METHODS: Data collected from consecutive inpatients who underwent EML in a UK teaching hospital over a 3-month period included perioperative physiology, treatment, morbidity, and mortality (30-day, in-hospital, 12-month, and 24-month). Univariate and multiple logistic regression analyses were used to identify predictors of mortality. RESULTS: Eighty-five patients (44 male) with a mean ± SD age of 61 ± 18 years were studied. Postoperatively, 51 % of patients were admitted to the intensive care (ICU) or the high-dependency unit (HDU). 30-day, in-hospital, 12-month, and 24-month mortality was 14, 16.5, 22.4, and 25.9 %, respectively. After adjusting for confounding variables, age ≥70 years (odds ratio [OR] = 9.2, P = 0.004) and a need for postoperative ICU/HDU (OR = 15.0, P = 0.014) were independent predictors of 30-day mortality. Independent predictors of in-hospital mortality were age ≥70 years (OR = 18.2, P = 0.016), ASA ≥III (OR = 22.1, P = 0.034), preoperative sepsis (OR = 20.6, P = 0.045), and need for postoperative ICU/HDU (OR = 21.5, P = 0.038). Independent predictors of 12-month mortality were preoperative urea >7.5 mmol/L (OR = 3.5, P = 0.038) and need for postoperative ICU/HDU (OR = 3.7, P = 0.044). Age ≥70 years was the only independent predictor of 24-month mortality (OR = 4.5, P = 0.014). Almost all deaths recorded in the 24 months following surgery resulted from disseminated malignancy. CONCLUSION: Patients who underwent EML had favourable outcomes, with 2-year survival close to 75 %. Age ≥70 years and the need for postoperative ICU/HDU care were independent predictors of mortality.

Adjunctive use of the ketogenic diet in a young adult with UBE2A deficiency syndrome and super-refractory status epilepticus.

The ketogenic diet (KD) may have a role in treating super-refractory status epilepticus (SRSE). Predominantly used in paediatric epilepsy, there are few reports of its use in adults. We describe a 19-year-old man with UBE2A deficiency syndrome, drug resistant generalized epilepsy, and severe intellectual disability, who developed SRSE. Initiation of the KD on day 81 of his intensive care unit stay and achieving a state of ketosis seven days later resulted in SRSE resolution and discharge from hospital and recovery to his normal cognitive state. Initiating the KD required a multidisciplinary team for diet initiation and carer education. The KD requires a prospective study of efficacy for SRSE and this should include adult patients.

Increased oxygen administration improves cerebral oxygenation in patients undergoing awake carotid surgery.

BACKGROUND: During regional anesthesia for carotid endarterectomy (CEA), 10% to 15% of patients develop signs of cerebral hypoxia after cross-clamping, manifested as changes in speech, cerebration or contralateral motor power. Reversal of such neurological deficits using administration of 100% O2 has been described. We used near-infrared cerebral oximetry to assess whether 100% O2 reliably improves regional cerebral oxygenation (rSO2) during carotid cross-clamping. METHODS: Sixteen patients undergoing awake CEA were studied. Bilateral rSO2 optodes were applied before the initiation of sedation and the conduct of the regional blockade. Patients received 28% oxygen by Venturi facemask. Perioperative blood pressure was maintained at or within 10% above the patient's normal limits during carotid cross-clamping. After cross-clamping, 100% O2 was administered for 5 min by a close-fitting anesthetic facemask. The O2 mask was then removed and the patient breathed room air. The effects on rSO2 readings and arterial blood gases were observed after each intervention. RESULTS: Data were analyzed for 15 patients. Ipsilateral rSO2 values decreased by 7.4% +/- 5% after carotid cross-clamping. Administration of 100% O2 resulted in an increase in ipsilateral rSO2 in all patients of 6.9% +/- 3.3% (range, 1%-12%) (paired t-test, P < 0.001) over the cross-clamped value while receiving 28% O2. Hemodynamic variables and arterial PaCO2 values were unaltered. CONCLUSION: With the carotid cross-clamped, ipsilateral rSO2 was reliably increased by the administration of 100% O(2) compared with 28% O2. The etiology of this increase is unclear, but may relate to the associated increase in O2 content of the blood or to an improvement in cerebral blood flow. Thus administration of 100% O2 during carotid cross-clamping may be beneficial for all patients undergoing CEA.

Two decades of British newspaper coverage regarding do not attempt cardiopulmonary resuscitation decisions: Lessons for clinicians.

OBJECTIVE: To review UK newspaper reports relating to Do Not Attempt Cardiopulmonary Resuscitation (DNACPR) decisions in order to identify common themes and encourage dialogue. METHODS: An online media database (LexisNexis(®)) was searched for UK Newspaper articles between 1993 and 2013 that referenced DNACPR decisions. Legal cases, concerning resuscitation decisions, were identified using two case law databases (Lexis Law(®) and Westlaw(®)), and referenced back to newspaper publications. All articles were fully reviewed. RESULTS: Three hundred and thirty one articles were identified, resulting from 77 identifiable incidents. The periods 2000-01 and 2011-13 encompassed the majority of articles. There were 16 high-profile legal cases, nine of which resulted in newspaper articles. Approximately 35 percent of newspaper reports referred to DNACPR decisions apparently made without adequate patient and/or family consultation. "Ageism" was referred to in 9 percent of articles (mostly printed 2000-02); and "discrimination against the disabled" in 8 percent (mostly from 2010-12). Only five newspaper articles (2 percent) discussed patients receiving CPR against their wishes. Eighteen newspaper reports (5 percent) associated DNACPR decisions with active euthanasia. CONCLUSIONS: Regarding DNACPR decision-making, the predominant theme was perceived lack of patient involvement, and, more recently, lack of surrogate involvement. Negative language was common, especially when decisions were presumed unilateral. Increased dialogue, and shared decision-making, is recommended.

Prolonged Refractory Hypotension following Combined Amlodipine and Losartan Ingestion Responsive to Metaraminol.

Introduction. Overdose with the calcium channel blocker amlodipine can cause profound hypotension that may be exacerbated by the concurrent ingestion of an angiotensin II receptor antagonist. Best management of such overdoses is uncertain although the use of hyperinsulinaemia-euglycaemia (HIE) has been recommended. Case report. We report a case of mixed amlodipine and losartan overdose in a 50-year-old lady. Severe hypotension was resistant to conventional vasopressors and high-dose insulin/euglycaemia, but did respond to a metaraminol infusion. Conclusion. A trial of metaraminol early in severe cases of calcium channel blocker and angiotensin II receptor antagonist toxicity may be of benefit, especially when conventional ionotropic treatment measures are failing.
