Sedation for ambulatory endoscopy.

Diagnostic and therapeutic fiberoscopy of gastrointestinal tract is often performed ambulatory and sedation is sometimes also required. Indication for sedation can be the intervention itself or the patient's psychological state. Aim of the study was to compare the effects of midazolam and combination of midazolam and fentanyl during endoscopy. Twenty eight cases were investigated: oesophagogastroduodenoscopy (n = 14) and colonoscopy (n = 14). Anaesthetics were midazolam (M) in 16 cases, midazolam-fentanyl (MF) in 12 cases. Non-invasive mean arterial pressure, pulse rate, acid-base balance and blood gases (by Astrup method) were recorded before endoscopy, at the 5th and 10th minutes of endoscopy, 15 minutes after intervention and also before emission. Pulse rate changed between 78-92/min. Mean arterial pressure appeared between 84-90 mm Hg. In MF group both were lower but there was not significant difference between the groups. The values were in normal range, there were not metabolic acidosis which needed correction. Onset of sedative effect was 2.8 min. in M group, 2.3 min. in MF group. The ability for adequate reaction returned within 11 min. in M group, within 14 min. in MF group. Fentanyl prolongs sedative effect of midazolam and offers sufficient pain relief. After 3 hours, patients could be emitted from the hospital.

[Risk factors of infected pancreatic necrosis, its microbiology and antibiotic treatment].

Acute pancreatitis is associated with greater and smaller necrosis in 20% of the cases. The lethality rate of sterile and infected necrosis is 10 and 15-40%, respectively. The results of a retrospective and a prospective study in acute pancreatitis have been analyzed in this study. Twenty patients suffering from infected necrosis due to acute necrotising pancreatitis were selected into the retrospective study. They were divided into two groups: Group 1 (N = 10) survivors, Group 2 (N = 10) those who died. The fate of patients was determined by their age, the severity of pancreatitis, and the effectiveness of the operation. In a prospective study 63 patients were operated due to benign pancreatic disease with fluid collection. Microbiological samples were taken during surgery in every case. It could be stated that the Enterobacteriaceae spp. play the principal role in the infection, and the anaerobic bacteria occur sporadically. The omission of bacteriological sample taking during surgery frustrates the targeted antibiotic treatment. The blood culturing may have useful contribution. The targeted antibiotic therapy based on relevant microbiological sample taking is substantial complementary of the surgical intervention in the treatment of the inflammatory pancreatic diseases.

Anaesthesiological indications and contraindications of minimally invasive surgery.

Spreading of laparoscopic techniques caused changes in anaesthesiological contraindications. In the first period laparoscopy was contraindicated in ischemic heart disease (IHD). Early mobilisation and short postoperative period are positive goals, IHD was taken out of contraindications. Present study compares changes in circulatory, blood gas and acid-base balance values during laparoscopic cholecystectomy (LC) in groups of patients ASA I-II. and ASA III. with IHD. There were 30 patients in group ASA I-II, 30 patients with IHD in category of ASA III. investigated during LC. Fifteen patients of both groups went under Propofol-Fentanyl (TIVA) anaesthesia, others were on Propofol-Fentanyl-N2O (IVA) protocol. All of them got also Atracurium. Pulse rate, mean arterial pressure, O2 saturation and end tidal CO2, blood gases and acid-base state were recorded before induction, after CO2 insufflation, after desufflation, 1 and 3 hours postoperatively. After CO2 insufflation there was a moderate tachycardia in both ASA III. groups (74/min-->88/min). In all groups pCO2 increased (40-->48 mmHg) but normalised till the 3rd postoperative hours (42 mmHg). Ventricular extrasystoles appeared in 3 ASA III. patients in IVA group. Three high risk patients had serious metabolic acidosis postoperatively. Present time the ischaemic heart disease does not contraindicates laparoscopic interventions. TIVA with Propofol is better choice because of its favourable effects on circulation and acid-base balance. Using N2O caused higher grade of intestinal distension. The cardio-respiratory, blood gas parameters and acid-base balance have to be monitorised in perioperative period of laparoscopic surgery.

Retinopathy of pancreatitis indicates multiple-organ failure and poor prognosis in severe acute pancreatitis.

During hospitalization for severe acute necrotizing pancreatitis, a connection between the onset of retinopathy of pancreatitis and multiple-organ failure was studied. Ophthalmoscopy was repeated every second day and continuous staging for multiple-organ failure was performed in 38 patients. Typical retinopathy of pancreatitis developed in 7 of 10 patients with multiple-organ failure and only in 4 of the 28 patients without multiple-organ failure. Retinopathy of pancreatitis was observed in 7 of the 18 cases leading to lethal outcome and only in 4 of the 20 surviving patients. No correlation was observed between the development of retinopathy of pancreatitis and hemodialysis, pre-existing diabetes mellitus, abnormal platelet count, result of hemoculture, c reactive protein value, fraction of inspired oxygen and adult respiratory distress syndrome. In the 21 control patients in grave general state but without acute pancreatitis, retinopathy of pancreatitis was never observed. In our prospective study the onset of retinopathy of pancreatitis had clinical prognostic value and indicated multiple-organ failure and poor prognosis in severe acute necrotizing pancreatitis.

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.
