[New intraoperative diagnostic methods in parathyroid surgery: intraoperative measurement of parathyroid hormone]. / Mútét alatti új diagnosztikus módszerek a mellékpajzsmirigy-sebészetben: intraoperatív parathormonszint-ellenórzés.

In thirty-seven patients undergoing parathyroidectomy from November 1999 to July 2000 with diagnosis of primary hyperparathyroidism the intraoperative intact parathyroid hormone level were studied. Preoperative samples of blood were taken from a peripheral vein before the beginning the operation. The second sample was taken 5 minutes after removal of parathyroid adenoma. The plasma intact parathyroid hormone concentration was measured by quick IRMA method. The preoperative high PTH levels reduced after excision of adenoma to the mean 18%. 33 patients had normal PTH levels after 5 minutes of removing. The total measuring time of quick PTH assay was about 30 minutes. The QPTH assay was a quantitative adjunct for the surgeon to ensure a successful parathyroidectomy. When the intraoperative QPTH level is not reduced to 50%, then the exploration should be continued and the probability of reoperation is decreased. They propose the application of the routine intraoperative measurement of QPTH level in all parathyroidectomy.

[Procalcitonin rapid test in surgical patients treated in the intensive care unit]. / Procalcitonin gyorsteszt alkalmazása sebészeti intenzív osztályon kezelt betegeknél.

Procalcitonin test (PCT) has been proposed to check severity of generalized infections or sepsis. The authors measured the PCT values with PCT-Q quick test (BRAHMS DIAGNOSTICA GmbH, Berlin) at 14 surgical patients treated in their intensive care unit (7 sepsis, 4 peritonitis, 2 localized pancreatic abscess, 1 postoperative fever). At 3 septic patients (2 pancreatitis, 1 intestinal necrosis) they measured the PCT levels repeatedly during treatment. In 2 patients with localized pancreatic abscess and in 1 patient with postoperative fever without evidence of infection the PCT levels were low (< 0.5 ng/ml). At 4 patients with peritonitis following gastric or colon perforation the PCT levels were highly elevated (> 10 ng/ml). At 7 patients with severe sepsis the PCT values were high (> 2 ng/ml), except for 1 patient with intestinal necrosis. At this patient the PCT levels were repeatedly low. In 2 septic patients with pancreatitis elevated PCT levels indicated the need for surgery. In most patients PCT was a good indicator of generalized infections. PCT levels measured repeatedly in sepsis were lower than in patients with peritonitis.

General anaesthesia for laparascopic adrenalectomy.

Surgical treatment of adrenal disorders is increasingly performed under laparascopic approach. Both pneumoperitoneum and adrenal tumour manipulation may induce haemodynamic variations. The aim of this study was to compare the inhalational and intravenous anaesthetic management for laparascopic adrenalectomy. Between 1977 and 1999 there were performed 28 laparascopic adrenalectomies. At patients with functioning adenoma and hypertension the anaesthesia was maintained with isoflurane in 8 cases and sevoflurane in 6 cases, et 14 patients with non-functioning adrenal masses with propofol and fentanyl (TIVA). In addition to the circulatory and respiratory monitoring there were made serial laboratory determinations (acid-base state, serum potassium, blood glucose) during the operation. On the basis of measured parameters isoflurane and sevoflurane anaesthesia proved to be favourable in case of functioning adrenal adenoma and TIVA with propofol and fentanyl in case of non-functioning adenoma.
