Pulmonary CO2 elimination during surgical procedures using intra- or extraperitoneal CO2 insufflation.

We examined end-tidal CO2 tension (PETCO2) and pulmonary CO2 elimination of CO2 (VECO2) during CO2 insufflation under general anesthesia for three surgical procedures: gynecologic laparoscopy (intraperitoneal CO2 insufflation for 43 +/- 4 min), laparoscopic cholecystectomy (intraperitoneal CO2 insufflation for 125 +/- 14 min), and pelviscopy (extraperitoneal CO2 insufflation for 45 +/- 3 min). All patients (10 in each group) underwent controlled mechanical ventilation. Oxygen consumption (VO2) and VECO2 were measured at 2-min intervals by a system using a mass spectrometer. For the three surgical procedures, VO2 remained stable, whereas VECO2 and PETCO2 increased in parallel from the 8th to the 10th min after the start of CO2 insufflation. A plateau was reached 10 min later in patients having intraperitoneal insufflation, whereas VECO2 and PETCO2 continued to increase slowly throughout CO2 insufflation during pelviscopy. During pelviscopy, the maximum increase in VECO2 and PETCO2 (76 +/- 5% and 71 +/- 7%) was significantly more pronounced than that observed during cholecystectomy (25 +/- 4% and 25 +/- 4%) and gynecologic laparoscopy (15 +/- 3% and 12 +/- 2%). The authors conclude that CO2 diffusion into the body is more marked during extraperitoneal than during intraperitoneal CO2 insufflation but is not influenced markedly by the duration of intraperitoneal insufflation.

[Hospital infection in the maternity department. 3 years of surveillance in 9,204 deliveries of which 1,333 were cesarean sections].

Hospital or nosocomial infection, or infection acquired in hospitals, is a health problem in all hospital departments and particularly in the maternity department. We report on a prospective survey of surveillance of hospital-acquired infections both from the mother and the baby's point of view after delivery vaginally or with caesarean carried out at the obstetrical clinic of the Edouard Herriot Hospital in Lyon (France) over three successive years with a series of 9,204 deliveries. The incidence of infection in women who were delivered without caesarean section was 1.37% when urinary tract infections had been excluded but 13% in women who had caesarean sections. Endometritis, skin infections and urinary tract infections were the leading causes. As far as the newborn were concerned, hospital infection ran at about 2.60% and this in the main was due to staphylococcal pustules in the skin. These figures are still too high and prevention should be based on more information given and more care taken by the whole staff of such a hospital.

[Cesarean section before the end of 32 weeks of amenorrhea].

The authors report the results of 59 caesarean operations in which 74 children were born before the end of the 32nd week of amenorrhoea. The gross mortality was 21.9% and the corrected mortality 18.5%. 7.9% of the infants had major neurological sequellae and 8.6% mild sequellae. 65.2% are alive and well with normal psychomotor development. The follow-up has been between 1 and 5 years. The factors that influence survival and the indications for caesarean section at this time are reviewed and discussed.

[Severe postpartum hemorrhage].

The authors report 95 cases of post-partum haemorrhage estimated at one litre or more seen in the Department of Obstetrics between 1979 and 1982 for 11 662 deliveries. Classical treatment combining artificial delivery or uterine manual evacuation-oxytocics led to the arrest of bleeding in 73 cases. Severe haemorrhage persisted in 22 cases, including 13 patients who were found to be suffering from a coagulopathy. Treatment of these severe forms is based upon: local haemostasis (in the presence of inertia, prostaglandins must be used before surgery) and correction of the coagulation disorder by substitution therapy providing the missing factors.

[Hospital infection in maternity homes].

The results of the prospective survey of hospital infections in mothers and newborns at the obstetrical clinic of the Edouard Herriot Hospital in Lyon are presented. Surveillance lasting six successive years covered 18,026 deliveries with or without the use of cesarean section. The incidence of hospital infections (not taking into account cases of bacteriuria) was 1.6% in parturient women not subjected to cesarean section and 11.7% in those having had this operation. Urinary tract and parietal infections, endometritis were in leading cases. The average incidence of hospital infection in newborns was 2.68%, the leading clinical manifestations being peripheral staphylococcal lesions in the form of pustules.
