Preoperative testing routines for healthy, asymptomatic patients in the Canary Islands (Spain)

OBJECTIVES: To analyze patterns of routine testing before elective/scheduled surgery in healthy/asymptomatic patients classified as ASA I or II according to the American Society of Anesthesiologists. MATERIAL AND METHOD: A questionnaire on the organization of preoperative testing was completed by anesthesiologists at five public hospitals in the Canary Islands. The questionnaire emphasized the most commonly ordered screening procedures, such as chest X-rays, electrocardiograms, laboratory tests and spirometry. RESULTS: Red cell counts were most frequently requested (for 86% of the patients), followed by platelet counts (80%) and blood chemistry (75%) and coagulation studies (72%). Least requested were urine tests and spirometry. The frequencies of electrocardiogram and chest X-ray requests fell between the two extremes, with patient age and the presence of certain indications seeming to affect whether those tests would be ordered or not. The need for such screening was perceived to increase for patients over 40 years of age. The ordering of preoperative tests varied from hospital to hospital and among anesthesiologists at a single site in spite of established protocols. CONCLUSIONS: Hospitals and individual anesthesiologists differ considerably in how they request preoperative tests. The variations can not be explained solely by differing patient needs given that respondents were contemplating only healthy/asymptomatic individuals undergoing relatively simple procedures.     

External progressive ophthalmoplegia secondary to mitochondrial myopathy. Report of a case and review of the literature

Progressive limitation of occular motility, accompanied by ptosis but usually without diplopia, occurs in many pathologic states, including mitochondrial diseases. A case with chronic progressive external ophthalmoplegia with onset during childhood, associated with proximal myopathy and dysphasia is presented. The muscle biopsy showed a myopathic pattern and abnormal subsarcolemmal mitochondrial deposits. Muscle biopsy for important in the correct diagnosis of this entity.     

Acute bulbar palsy due to myelomeningocele and Chiari II malformation

We describe a case of a 10-year-old girl with myelomeningocele and type II Chiari malformation. She presented with an acute bulbar palsy requiring mechanical ventilation. Surgical decompression of the brainstem was performed and, because of a phrenic nerve palsy, surgical plication of the right diaphragm was also required. The patient s evolution was favourable. We discuss the various forms of clinical presentation of this pathology as well as its management. The importance of early diagnosis and surgical correction are also stressed as a key factor for favourable evolution.
