Anesthetic Management During Pediatric Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy With Cisplatin in a Small Child: A Case Report and Systematic Literature Review.

Cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy (HIPEC) present a challenging task for anesthesia providers. Anesthesia management may be complicated by hyperthermia, fluid shifts, and distinct inflammatory response. Only a few reports dealing with the anesthesia management of pediatric CS and HIPEC have been published. We report a case of a 2-year-old child with a relapse of an alveolar rhabdomyosarcoma of the uterus and peritoneal carcinomatosis treated with CS and HIPEC. For children, careful temperature measurement, intraoperative prevention of hyperthermia, and sufficient volume management are important, as well as postoperative pediatric intensive care with experience CS and HIPEC patients.

LMA Protector™ Airway: first experience with a new second generation laryngeal mask.

BACKGROUND: The LMA Protector™ Airway (The Laryngeal Mask Company Ltd., Teleflex Incorporated, Athlone, Ireland) is a new supraglottic airway promising a better seal, an improved drainage of gastric secretions and the opportunity of a simplified fiberscopy-guided tracheal intubation. The aim of this study was to present a primary evaluation of the LMA Protector in a clinical setting. METHODS: After informed consent 50 patients, scheduled for minor/moderate surgery in supine position, were recruited. Pharyngeal seal pressures were examined in neutral position of the patients' head and in maximum passive extension of the neck. Additionally, the fiberscopic view on the glottis was graduated and the feasibility of fiberscope guided tracheal intubation through the device was evaluated. RESULTS: The median pharyngeal seal pressure of the LMA Protector in neutral position of the head was 34 cmH2O. Passive extension of the neck did not cause a reduction of the pharyngeal seal (median pharyngeal seal pressure: 34.7 cmH2O; P<0.039). The LMA Protector was applicable for fiberscopic tracheal intubation but is not reliable for blind tracheal intubation. CONCLUSIONS: The LMA Protector provides a high pharyngeal seal. Uncommon for laryngeal masks its pharyngeal seal is not affected by the extension of the patient's neck. As a second generation supraglottic airway which is also suitable for simplified fiberscopic guided tracheal intubation, the LMA Protector could be considered as a supraglottic airway of the third generation.

Fecal elastase 1 and vitamin D3 in patients with osteoporotic bone fractures.

BACKGROUND AND AIMS: The aim of the present study was to clarify if patients with osteoporotic bone fractures have exocrine pancreatic insufficiency, especially reduced fecal elastase 1, connected with lowered serum levels of vitamin D3 that could be relevant for predominant osteoporosis. METHODS: Between October 1999 and September 2001, we investigated on 167 patients with an average age of approx. 69 years suffering from typical osteoporotic bone fractures, as well as 20 healthy controls with an average age of 53 years. A standardized osteodensitometry via dual energy X-ray absorptiometry (DEXA) was performed in all participants. Levels of PTH, 1,25(OH)(2) Vitamin D(3), 25(OH) Vitamin D(3), calcium and phosphate in serum, elastase 1 in feces as well as the body mass index were determined in all patients and controls. RESULTS: In patients 25(OH)D3 was more than 60% and 1,25(OH)(2)D(3) was more than 53% decreased compared to controls. Fecal elastase 1 was lower than the lowest reference of 200 microg/g feces in more than 34% of the patients and it was more than 65% reduced in comparison to healthy controls (fecal elastase 1 patients: 240.7 +/- 96.3 microg/g; controls 694.9 +/- 138.6 microg/g). Separation of the patients in accordance with the elastase 1 contend in feces into four groups (below 100 microg/g, between 100 and 200 microg/g, between 201 and 300 microg/g and above 300 microg/g) resulted in significant variations for 25(OH)D(3), 1,25(OH)(2)D(3), calcium and PTH between these groups (p < 0.01). Furthermore 25(OH)D(3), 1,25(OH)(2)D(3), calcium and PTH correlated significantly with elastase 1 in feces (p < 0.01) the way, that lower fecal elastase 1 was connected with lower levels of the other parameters. BMI shows no relevant differences within the patients or between patients and controls. CONCLUSION: Exocrine pancreatic insufficiency, especially lowered fecal elastase 1, may be much more frequent in patients with osteoporotic bone fractures than suggested so far. Lowered exocrine pancreatic function with lowered fecal elastase 1 seems to be relevant as a reason for reduced levels of circulating vitamin D3 metabolites being an appropriate additional cause for predominant osteoporosis.
