Dental attendance in a sample of pregnant women in Birmingham, UK.

One of the broader aims of antenatal care is to enhance the general health of the mother, and free dental treatment during pregnancy gives an opportunity for the mother's dental health to be improved. In this study, 500 mothers at the Birmingham Maternity Hospital were interviewed, using a questionnaire, during their first three days postpartum. The object was to investigate the receipt of dental care during pregnancy. Only 304 (61 per cent) mothers had visited the dentist in the antenatal period and 196 (39 per cent) had not. Although the majority of mothers (95.5 per cent) were aware that dental care was free, the high non-attendance rate was because mothers 'did not feel it necessary' to visit. Therefore the removal of the financial deterrent does little to promote dental attendance. Previous patterns of dental attendance strongly influenced attendance behaviour during pregnancy. Non-attenders tended to be Muslims, mothers who were previously irregular attenders, those of lower socio-economic groups, and those having their first baby. Efforts to improve the uptake of dental care should be directed towards these groups, and all the health agencies involved in antenatal care can contribute to the promotion of better maternal health.

A study of the dental health of patients undergoing heart valve surgery.

The mouth is a possible source of infection in patients receiving prosthetic heart valves. In this study, the dental health of such patients was found to be very poor. Whilst most of the patients were asymptomatic, only two were dentally fit and 65% required the extraction of one or more teeth. On average, patients had not attended a dental practice for more than 9 years. This level of dental neglect, in a group of patients particularly at risk, is alarming and this study indicates that a higher standard of oral care is still required and that a lack of symptoms does not indicate dental fitness.

The effect of smoking on immediate post-extraction socket filling with blood and on the incidence of painful socket.

The effect of habitual smoking on post-extraction socket filling with blood and on the incidence of painful socket, was investigated. Data were collected from 2417 adult dental out-patients in whom 3541 extractions were performed under local anaesthesia. Post-operative socket filling with blood was significantly reduced in smokers, compared with non-smokers (p less than 0.01). There was a higher incidence of painful socket in heavy smokers (20 or more cigarettes per day), compared with nonsmokers (p less than 0.05). There was a significant relationship between immediate post-extraction socket blood level and the incidence of painful socket; sockets which showed poorer filling were more likely to develop painful socket (p less than 0.02). Smoking appeared to have an adverse effect upon the healing of extraction wounds.

Intraoperative cardiovascular crisis caused by glucagon.

Glucagon use as a muscle relaxant is common in radiologic and endoscopic examinations in which smooth-muscle spasm has interfered. Glucagon also provokes catecholamine release from an unsuspected pheochromocytoma, as occurred in a 60-year-old patient undergoing biliary tract surgery. To prevent hypertensive crisis and ventricular tachyarrhythmia after intraoperative glucagon administration, appropriate pharmacologic catecholamine antagonists must be immediately available.

Local anaesthesia and dry socket. A clinical investigation of single extractions in male patients.

1533 single intra-alveolar permanent tooth extractions in males were investigated in a study to determine if the type and technique of local anaesthesia influenced the occurrence of dry socket. The results show that the incidence of dry socket was significantly greater after the use of Xylocaine compared to Citanest and that the use of repeated injections or intraligamental techniques increased the likelihood of this painful post-extraction condition.

Halothane and isoflurane do not decrease PaO2 during one-lung ventilation in intravenously anesthetized patients.

We examined the effect of the inhalational anesthetics halothane (H) and isoflurane (IF) on arterial oxygenation during one-lung ventilation. Twenty consenting patients who required thoracotomy and one-lung ventilation were initially anesthetized only with the intravenous agents, diazepam, fentanyl, pancuronium, metocurine, and infusions of either ketamine or methohexital. A double lumen endotracheal tube was inserted, and each patient's lungs were mechanically ventilated (two-lung ventilation, step 1) with 100% O2 while the patient was in the lateral decubitus position. After the pleura was opened, the nondependent lung was collapsed while the dependent lung continued to be ventilated with 100% O2. After serial PaO2 measurements indicated achievement of stable one-lung ventilation conditions (step 2), intravenous anesthetic agents were discontinued, and either H (n = 10) or IF (n = 10) was administered (step 3) so that PETH = 7.70 +/- 0.61 mm Hg and PETIF = 9.89 +/- 1.08 mm Hg for more than 15 min; at the end of step 3, PaH/PETH = 0.82 (n = 5), PaIF/PETIF = 0.75 (n = 5), PvH/PETH = 0.64 (n = 3), and PvIF/PETIF = 0.68 (n = 3). The inhalational anesthetics were then discontinued, and intravenous agents were reinstituted, allowing PETH and PETIF to decrease below 0.50 mm Hg (step 4). Two-lung ventilation was resumed at the end of the surgical procedure (step 5). PaO2 decreased from 441 +/- 64 to 252 +/- 70 mm Hg when one-lung ventilation was achieved (steps 1-2), and PaO2 increased from 258 +/- 72 to 395 +/- 65 mm Hg when two-lung ventilation was resumed (steps 4-5).(ABSTRACT TRUNCATED AT 250 WORDS)
