Evaluation of a dental care program for school beginners in a Paris suburb.

OBJECTIVES: Dental care for children is available in France, but the method of administration is cumbersome: care is generally provided by private dentists, and parents can claim reimbursement of at least 70% of the costs afterwards. In the Département of Val d'Oise (north of Paris and including some densely populated suburbs), a scheme is in place to provide 100% reimbursement. To encourage participation, schoolchildren are screened by dentists who advise if treatment is needed. The objective of this study was to ascertain the effectiveness of screening as a stimulus for seeking dental care. METHODS: In two towns, 6-7-year-old schoolchildren were cluster-sampled to give 507 participants. At screening, about half of the participants were found to be in need of operative treatment. Questionnaires about demographic and other background factors were sent home. From those needing treatment, 186 (77%) sets of questionnaires were returned. These persons were the analytical basis of the study. Six months after screening, the 186 participants were examined to estimate whether they had sought and received treatment as advised. RESULTS: The majority of the participants came from low socioeconomic and deprived backgrounds. Most of the parents were born in countries outside Europe. Only about one-quarter of the children advised to seek treatment had actually done so after 6 months. Slightly under half of those who were treated had claimed the reimbursable amount after the treatment. Of the 186 participants needing treatment, 24% had more than 4 dt + DT but 70% of these had not received any care. CONCLUSION: These findings suggest that even when costs are totally reimbursed, most children in need of care do not receive it; the greater the need of care, the lower the likelihood of getting it. The deprived people and immigrants frequently inhabiting the Parisian suburbs seem to experience cultural, financial, linguistic, and administrative barriers to care, which impede uptake and which must be changed if these children are to enjoy improved dental health.

Randomized study of intravenous fluid preload before epidural analgesia during labour.

We performed a randomized controlled trial of the effect of intravenous fluid preload on maternal hypotension and fetal heart rate (FHR) changes in labour after the first epidural injection. Group 1 (49 women) received 1 litre of crystalloid preload. Group 2 (46 women) received no preload. No statistically significant difference was shown between the two groups for either of the outcomes. Hypotension was found in three women in group 1 and five in group 2 (P = 0.4). Deterioration in FHR pattern was found in four women in group 1 and 11 in group 2 (P = 0.08). This study has not shown a significant increase in the incidence of hypotension when intravenous preload is omitted before epidural analgesia using a low concentration of bupivacaine during labour. Because of the clinical importance of the difference in the rate of FHR deterioration between the two groups, we continue to administer preload for high-risk cases.

Low dose combined spinal-epidural anaesthesia for caesarean section in a patient with peripartum cardiomyopathy.

A patient with peripartum cardiomyopathy was scheduled for elective caesarean section after stabilization on medical therapy. Wer performed a combined spinal epidural using one ml 0.5% hyperbaric bupivacaine (5 mg) with 0.3 mg diamorphine for the spinal. The epidural was topped up with 10 mL bupivacaine 0.5%. Significant haemodynamic changes consisted of reduction in heart rate and hypotension after the spinal, and tachycardia after delivery. The benefits and risks of this approach are discussed.

Rocuronium is the best non-depolarizing relaxant to prevent succinylcholine fasciculations and myalgia.

PURPOSE: To determine which non-depolarizing relaxant among d-tubocurarine, vecuronium, atracurium, mivacurium and rocuronium prevented muscular fasciculations and myalgia following succinylcholine. METHODS: In this double blind randomized study, 120 female patients scheduled for laparoscopic procedures were studied. They were divided into six groups of 20 according to the non-depolarizing pretreatment used: NaCl 0.9% (control), 0.05 mg.kg-1 d-tubocurarine, 0.01 mg.kg-1 vecuronium, 0.05 mg.kg-1 atracurium, 0.02 mg.kg-1 mivacurium and 0.06 mg.kg-1 rocuronium. Four minutes after the pretreatment, 1.5 mg.kg-1 succinylcholine was injected. Side effects of the pretreatment, the presence and magnitude of fasciculations, the ease of tracheal intubation, myalgia 1, 24 and 48 hr after surgery were observed. A Puritan Bennett Datex 221 NMT Relaxograph monitor was used to evaluate the neuromuscular block. RESULTS: Muscle fasciculations were observed in 19 of the 20 patients in the control group and in 3 of the 20 patients in the rocuronium group, the best of the pretreatments in that aspect. Four patients in the mivacurium group were unable to sustain more than four seconds head-lift after pretreatment (P < 0.05). Tracheal intubation conditions were better and the onset of block was faster and longer after succinylcholine in the control group (P < 0.05). Myalgias were present in 71% of the patients 24 hr postoperatively and the frequency was not different among the groups. CONCLUSION: Among the pretreatments tested, 0.06 mg.kg-1 rocuronium was the best to prevent muscular fasciculations following succinylcholine injection. In the population studied, pretreatment did not prevent postoperative myalgia. Succinylcholine 1.5 mg.kg-1 was more effective without a non-depolarizing pretreatment.

Prophylaxis in cardiac surgery. A controlled randomized comparison between cefazolin and cefuroxime.

In a prospective randomized two center trial, short-term prophylaxis with cefuroxime (CFX) in 189 patients was compared with cefazolin (CFZ) in 196 patients submitted to elective cardiac surgery. A total of 3 g was administered over 24 h in both groups. One major adverse reaction with CFX was noted. Patients were prospectively screened by infectious disease nurses for surgical wound and secondary infections. Sternal wound infections occurred in eight patients treated with CFX and all were minor. One patient from this group eventually died of infectious causes. In the CFZ-treated patients two major and six minor wound infections occurred requiring extensive debridement in two. Secondary infections occurred less frequently in the CFX group (13.2 per 100) than in the CFZ group (16.8 per 100) with two infection-related deaths in the CFX and one in the CFZ group. The most commonly identified organisms were Staphylococcus aureus and a variety of gram-negative organisms. No major differences were observed between the CFX and CFZ groups. Short-term administration of 3 g CFZ or CFX in this study could not demonstrate the advantage of one of the antibiotics used over the other in terms of clinical outcome, incidence or site of infection or organisms identified. The 24 h administration of 3 g CFZ or CFX provided suboptimal prophylaxis for wound infection or secondary infections in patients undergoing elective open heart surgery.
