[Infra-orbital nerve block in early primary cheiloplasty].

A prospective study have studied the effect of infraorbital block during anesthesia in infants with a cleft lip. The study was conducted during the year 1994, in the hospital Necker Enfants-malades. During this period 51 cleft lip surgery were performed. Anesthesia for infants with cleft lip using bilateral infraorbital block is a safe, simple and quick technique, and result in a good longlasting analgesia, seems to decrease the risk of respiratory depression, and allows an immediate and comfortable awakening.

Autologous blood donation for elective surgery in children weighing 8-25 kg.

To determine whether autologous blood donation can be used safely and efficiently in children weighing 8-25 kg, we studied children whose perioperative blood losses were expected to exceed 25% of total blood volume. Blood donations were performed in pediatric units, under the direction of an anesthesiologist and a blood bank physician experienced in paediatric care. Twenty-four children, median age 6 years (1-13), were included. They underwent surgery mainly for digestive or urological disorders, and for orthopedic defects. Forty blood collections were performed of the 46 prescribed. Phlebotomies could not be performed in 1 child because of the mother's apprehension, and in 5 cases because of venous access problems. All phlebotomies were hemodynamically well tolerated. Hemodilution was also performed in 17 children, and cell saver used in 2. Allogeneic blood transfusion was avoided in 21/24 children.

Measurement of post-operative pain and narcotic administration in infants using a new clinical scoring system.

We developed a clinical neurologic and behavioral scoring system composed of 10 items to measure the post-operative pain levels in infants: (1) sleep during preceeding hour, (2) facial expression of pain, (3) quality of cry, (4) spontaneous motor activity, (5) Spontaneous excitability, (6) flexion of fingers and toes, (7) sucking, (8) global evaluation of tone, (9) consolability and (10) sociability. Using this system, a group of infants ranging from one to seven months in age and undergoing minor surgical procedures was studied. The infants were randomly assigned to two groups: Group I received Fentanyl intravenously (3 micrograms/kg) prior to surgery, and Group II received a placebo. The infants then were studied post-operatively in the recovery room at 30, 60, 90 and 120 min intervals. Over the entire post-operative observation period, 54% of the infants in Group I had satisfactory analgesia compared to 18% in Group II. There were no significant differences in Group I and Group II in oxygenation, carbon dioxide elimination, blood pressure, heart rate or temperature.

[Continuous spectrum analysis during anesthesia and the recovery period in infants under 1 year of age].

Continuous spectral EEG activity monitoring has been used in adults as a monitor of brain activity during anesthesia. It has not been used in infants. We studied 22 infants less than 7 months old undergoing minor surgery. Halothane alone or minimal Halothane anesthesia associated with caudal epidural anesthesia were used. Life-Scan analysis, in spite of wide individual variations, allowed us to detect infraclinical hypoxia episodes, it provided informations about operative confort, depth of anesthesia and added in the post-operative period an objective criteria to clinical evaluation of pain. A wide use of such a monitoring is warranted in infants.

[Induction anesthesia in the child].

The anesthesic induction in children must be technically carefully performed, but also in the child's mind. Inhalation has the advantage to be painless and easy to perform. It seems more advisable to allow the child to choice his own kind of induction. The experience of our institution is reported.
