[Hemodynamic effects of dobutamine in hyperkinetic septic shock treated with norepinephrine].
A prospective study of the haemodynamic effects of dobutamine was carried out in six men and four women suffering from hyperkinetic septic shock, already treated with noradrenaline and dopamine. All ten patients had septic shock, defined as a mean arterial blood pressure of less than 70 mmHg and an urine output under 15 ml.h-1, persisting despite fluid loading, associated with positive blood cultures, increased white blood cell counts, and a septic area. Initial treatment consisted in fluid loading, so as to increase cardiac output whilst keeping pulmonary wedge pressure (Ppw) between 8 and 10 mmHg. ⋯ The usual haemodynamic parameters were measured and calculated once a steady state had been obtained at each dose (within 20 to 30 min). Ppw was kept between 8 and 10 mmHg by fluid loading with a 4% albumin solution. At the beginning of the study, patients had a mean blood pressure of 78 +/- 6 mmHg, a CI of 4.8 +/- 1.5 l.min-1.m-2 and a RsaI of 1,285 +/- 341 dyn.s.cm-5.m-2 RsaI.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports[Peroperative massive pulmonary embolism of tumoral origin. Value of extensive monitoring].
A case is reported of a 47-year-old female patient who suffered from massive tumour embolism during a nephrectomy for a renal carcinoma invading the inferior vena cava. Intraoperative monitoring consisted in direct blood pressure measurement (radial artery cannula), central haemodynamic monitoring (Swan-Ganz catheter), pulse oximetry and capnography. During the surgical manipulation of the suprahepatic vena cava, Petco2 suddenly decreased (from 25 mmHg to 14 mmHg), together with Spo2 (from 99% to 89%), and the mean pulmonary arterial pressure increased from 18 mmHg to 40 mmHg. ⋯ The patient left the intensive care unit after twelve days. After one year of follow-up, no complication had occurred. The value of cardiopulmonary bypass in nephrectomy for renal carcinoma invading the vena cava, or the renal vein, is discussed.(ABSTRACT TRUNCATED AT 250 WORDS)

[Peripheral nerve block during ambulatory surgery of varicose veins].
This retrospective study of the 46 operations, carried out over a one year period for lower limb varicose veins using peripheral nerve blocks, included 45 patients (35 women and 10 men, mean age 49.3 years), all ASA 1 or 2, except for 4 elderly patients with a varicose ulcer (ASA 2 or 3). In 40 procedures, a sciatic nerve block combined with a "3 in 1" lumbar plexus block at the level of the groin (as described by Winnie) were used. In the remaining six, either a sciatic nerve block (short saphenous vein crossectomy; n = 3), or a "3 in 1" lumbar plexus block alone (short stripping of the long saphenous vein; n = 3) were required. ⋯ During the same period, nine similar procedures were carried out under general anaesthesia, and two under epidural anaesthesia. They included seven bilateral varicose veins, three patient refusals for peripheral nerve blocks, and one allergy to lidocaine. Already used for some procedures in orthopaedic and casualty surgery, peripheral nerve blocks seem to be well suited for surgery of unilateral varicose veins.

This study analyses 126 cases of dental injuries occurring during endotracheal intubation, reported to the service of litigations of the hospitals in Lyon over a ten-year period, and giving rise to a complaint. The overall rate was 1 out of 4,000 cases of intubation. The true incidence may be greater. ⋯ This device was tested in 108 patients. Intubation was easy with the device in place in 73.2% of patients; mouth opening was reduced by a mean of 4.2 +/- 0.5 mm. The device made intubation more difficult, and even impossible, in patients whose mouth opened no more than 3.5 cm.(ABSTRACT TRUNCATED AT 250 WORDS)
