Ketamine anesthesia with or without diazepam premedication for bone marrow punctures in children with acute lymphoblastic leukemia.

Ketamine is a drug widely used for analgesia and sedation of children for diagnostic and therapeutic procedures. The authors investigated in a randomized controlled clinical trial if diazepam premedication would have a beneficial effect on side effects related to ketamine anesthesia for bone marrow punctures (BMPs) in children with acute lymphoblastic leukemia (ALL). Sixteen children 4 years or older at the time of BMP were eligible. The first 2 BMPs after complete remission was obtained were studied. BMPs were performed under ketamine anesthesia (1.0-1.5 mg/kg i.v.), as usual. Patients were randomized to receive 1 h before the first BMP blinded, either diazepam or placebo orally and before the second BMP the other way round. Blood pressure, heart rate, and oxygen saturation were monitored, and patients were observed for signs of anxiety, pain, and other side effects. The patients were interviewed after each BMP and asked for their preference 1 week after the second BMP. Ketamine anesthesia appeared as safe and effective after diazepam premedication as after placebo premedication. From the interviews and questionnaires, it was clear that half of the children preferred diazepam premedication because of less awful dreaming and more gradual falling asleep and waking up. Diazepam premedication may be useful for selected children with ALL receiving ketamine anesthesia for BMPs.

[Better postoperative pain management in children by introduction of guidelines; a prospective study]. / Verbetering van de postoperatieve pijnzorg bij kinderen door invoering van richtlijnen; een prospectief onderzoek.

OBJECTIVE: To investigate the influence of recommendations on the quality of postoperative pain management in children. DESIGN: Prospective. SETTING: University Hospital Groningen, the Netherlands. METHOD: After interdisciplinary recommendations on postoperative pain were developed, the quality of postoperative pain management was investigated before implementation (phase I; n = 50 children aged 0-14 who underwent elective surgery), three months after the implementation (phase II; n = 51), and nine months later (phase III; n = 50). Quality was defined by a pain score (for ages 0 to 4 with the 'Children's Hospital of Eastern Ontario pain scale' (CHEOPS) and for ages 4-14 with the Oucher scale) and the prescription of analgetics: kind, dose, frequency, prescription by anaesthetist and doctor on the ward. Pain was scored every 2 hours during the first 24 hours after surgery. A CHEOPS score < or = 6 an Oucher score < or = 50 was defined as adequate; higher scores were defined as inadequate. RESULTS: Pain measurement showed a statistically significant improvement of pain scores in time (phase II and III compared with phase I: odds ratio: 2.5; 95% confidence interval: 1.03-6.00; p < 0.01). Searching for factors that could be responsible for this improvement, like medication, we found no statistically significant differences in everyday practice in phase II and III compared with phase I. However, children who could score their pain by self-report (Oucher) showed the best results in all 3 phases of the study. The youngest children, i.e. less than 6 months old, showed inadequate results during the whole study. The greatest improvement in time during the first 12 hours was seen in the group of children older than 6 months. The recommendations were followed more strictly in younger children, and when continuous morphine was given. CONCLUSION: Pain scores in children improved after the introduction of recommendations on postoperative pain. However, the improvement could not be attributed to factors like medication. Factors like a change in attitude towards pain could be responsible for this change.

[Analgesia in children in general pediatrics]. / Pijnbestrijding bij kinderen in de algemene pediatrie.

In recent years the knowledge of pain in pediatric patients has grown. Attitudinal changes and the development of assessment-scales also contributed to a better understanding of childhood pain. This article provides a guidance for the pharmacological management of pain in children.

Selective decontamination of the digestive tract contributes to the control of disseminated intravascular coagulation in severe liver impairment.

A premature neonate with severe Coxsackie B1 hepatitis acquired in utero developed disseminated intravascular coagulation a few days after birth. The neonate did not respond to conventional treatment. Eradication of aerobic gram-negative bacilli (Enterobacteriaceae) from the gut with oral nonabsorbable polymyxin E and tobramycin (selective decontamination of the digestive tract) was followed by clinical improvement; disseminated intravascular coagulation was controlled. After an unstable convalescence, the neonate recovered and was discharged in good general condition. A correlation between oral feeding, gut carriage of Enterobacteriaceae, fecal endotoxin pool, and platelet counts was observed. The eradication of gut carriage of aerobic gram-negative bacilli was associated with a significant decrease of the intestinal endotoxin pool and paralleled the recovery from thrombocytopenia. Selective decontamination is discussed as a method of possible value for controlling systemic endotoxin-induced symptoms in the critically ill with intestinal endotoxemia.

Neurological follow-up of 281 children born in breech presentation: a controlled study.

A study was conducted of all children delivered in breech presentation from 1969 to 1977 in the university's department of obstetrics. One-fifth of the deliveries were by caesarean section. Perinatal mortality was high (13.2%) but was due almost exclusively to causes other than the birth itself. The 256 surviving children and their matched controls were neurologically examined at 18 months or at ages varying between 3 and 10 years. The attrition rate was 5.7%, but in most cases data on development were available. Significant differences between the study and control groups existed for only minor neurological dysfunctions. It is concluded that the main danger of breech presentation is in the associated complications of pregnancy and that there is no reason to advocate a higher frequency of abdominal delivery than the 20% found in this study.
