We describe the case of a 24 year old woman, affected by haemorrhagic shock due to post-partum uterine atony, who underwent an emergency hysterectomy with persistent postoperative bleeding, successfully treated with recombinant activated factor VII (Novoseven).
We describe a clinical case of a 7 year old girl, affected by peritonitis, septic shock and multiorgan failure, treated successfully with drotrecogin alpha associated with conventional therapy.
OBJECTIVE: To determine the incidence of hypoxaemia and the efficacy of oxygen therapy in the early postoperative period. DESIGN: Prospective, randomized study. SETTING: Regional hospital. PATIENTS: 89 patients undergoing general anaesthesia divided into two groups, I (n = 45) and II (n = 44). INTERVENTIONS: Patients of group I breathed room air while patients of group II received supplementary oxygen. MEASUREMENTS AND MAIN RESULTS: Oxygenation was monitored continuously for 60 minutes with a pulse oximeter after the end of surgery; hypoxaemia was graded into four values of SpO2: mild (86-90%), moderate (81-85%), severe (76-80%), extreme (< or = 76%). One or more episodes of mild hypoxaemia were recorded in 68% of patients in group I and in 36% of patients in group II (p < 0.005); moderate hypoxaemia were recorded in 51% of patients in group I compared with 13% of patients in group II (p < 0.001). Episodes of severe or extreme hypoxaemia were recorded in 22% and in 6% of patients in group I; no patients in group II exhibited such small values of saturation. The smallest recorded SpO2 values were 81 +/- 5.94% in group I and 89 +/- 8.63% in group II (p < 0.001). CONCLUSIONS: There is a high incidence of clinically unsuspected hypoxaemia in the early postoperative period, the use of supplemental oxygen reduces but does not prevent hypoxaemic episodes, every patient should be monitored continuously with a pulse oximeter in the recovery room.
The authors describe their experience with imipenem-cilastatin in 36 patients in critical conditions due to multiresistant bacterial infections. The efficacy and tolerability of the antibiotic are stressed.

PURPOSE: The Complex Regional Pain Syndrome (CRPS) is a chronic pain state provoked by lesions of the soft tissues or of the bony tissues (type CRPS-I or reflex sympathetic dystrophy-RSD) or by lesions of the nerves (type CRPS-II or causalgia) with vegetative alterations (perspiration, vasomotory alterations) and trophic alterations (bony cutaneous atrophy, alopecia, articular contractures). The pharmacological block of the sympathetic nerves through a peripheral vein is inserted in the multidisciplinary approach that characterizes the therapy of this syndrome. MATERIALS AND METHODS: A retrospective survey was carried out on a group of 185 patients affected by RDS/CRPS with block of the sympathetic nerves through a peripheral vein with guanethidine. Superior limb: Inflation of the tourniquet till disappearance of the radial wrist. Cannulation of a peripheral vein with Butterfly needle n. 23. Guanethidine 10 mg, lidocaine 20 mg, sodic heparin 500 u.i, NaCl 0.9% 20 ml. Injection in 5 minutes. Permanence of the pneumatic tourniquet inflated above systolic blood pressure for 15 minutes. Deflation slowly. Inferior limb: Inflation of the tourniquet till disappearance of the pedidium wrist. Cannulation of a peripheral vein with Butterfly needle n. 23. Guanethidine 20 mg, lidocaine 40 mg, sodic heparin 1000 u.i, NaCl 0.9% 40 ml. Injection in 5 minutes. Permanence of the pneumatic tourniquet inflated above systolic blood pressure for 15 minutes. Deflation slowly. RESULTS: The first stage (hyperemic) showed the highest incidence of remissions: (83, 33%). Even in the second stage (dystrophic) the answer to the therapy has been fundamentally positive: (53, 68%). In the third stage (atrophic) the results have been more modest: (8, 33%). CONCLUSIONS: The block of sympathetic system with guanethidine is still an important method in the therapy of the CRPS; in fact it is surely less invading than the blocks of the stellate ganglion or of the lumbar sympathetic.
We describe the case of a patient admitted in intensive care, after cardiac arrest by ventricular fibrillation treated by electrical defibrillation, that showed a serious deficit of the cardiac index and increase of the systemic vascular resistances. The patient was treated by levosimendan (Simdax): a starter dose of 12 microg/Kg in ten minutes and then a continuous perfusion of 0.1 microg/Kg/min. for 24 hours. He had a continuous amelioration of the clinical conditions and of the hemodynamics parameters. In the fifth day the patient was transferred to the Cardiology department and after 20 days he was discharged from hospital.
