Cocaine and sudden cardiac death.

Cocaine may induce totally unexpected cardiotoxicity in young individuals at some time distant from the cocaine ingestion. Commonly, such individuals are asymptomatic for coronary artery disease; some have no demonstrable coronary artery disease even after the cardiac event. Those who use cocaine must be considered at risk of cardiotoxicity at any time after recent cocaine ingestion. Guidelines are suggested for clinical management in oral and maxillofacial surgery.

Nitrous oxide in dental practice.

Nitrous oxide has been widely employed by dentists as an anesthetic agent throughout its history of clinical use. While hypoxic general anesthetic techniques using nitrous oxide are rarely if ever employed today in the United States, and appear to be on the decline abroad, nitrous oxide is extensively and successfully used in dentistry as a conscious sedative to reduce anxiety and provide some supplemental analgesia. Less frequently it is used as a co-agent with intravenous anesthetics or sedatives during oral surgery or restorative dentistry. Considering the number of patients given this agent on a yearly basis, its relative lack of reported side effects when used appropriately is remarkable.

The combined effect of nitrous oxide and oxygen and electrical stimulation during restorative dental treatment.

A total of 124 adult patients were treated with nitrous oxide (N2O) and oxygen (O2), an electrical analgesic, or a combination of N2O/O2 and an electrical analgesic during restorative dental procedures. The use of electrical analgesic or N2O/O2 without local anesthetics resulted in a high failure rate and poor patient acceptance. However, combining N2O/O2 sedation with electrically induced analgesia resulted in a statistically significant improvement over either technique used alone, and provided an overall 81% success rate when used during restorative dentistry.

Death after chloral hydrate sedation: report of case.

A young healthy female died after taking chloral hydrate syrup before surgery to extract third molars. Various aspects of the use of chloral hydrate are discussed, including the metabolism, active moiety, reported side effects, and effects on the heart. Recommendations are made concerning patient supervision, dosage limitations, and degree of sedation.

Achieving oral health in patients with renal failure and renal transplants.

The protocols for oral evaluation and treatment of patients with renal failure and renal transplants are presented. Guidelines for dental treatment planning are outlined, and extraction versus conservation of teeth is discussed. Information on special considerations involving dialysis, antibiotic prophylaxis, drug therapy, and immunosuppression is provided. The goal of treatment is to restore maximum function while minimizing the risk of oral infection after transplantation.

Trace contamination of anesthetic gases: a brief review.

Data have been reviewed relevant to the effects of chronic exposure to trace quantities of inhalation anesthetic agents. Much circumstantial evidence exists indicating a probable hazard to the clinician administering these agents. However, all previous studies in man have not identified the potential hazard of nitrous oxide without the presence of other contaminating agents.

An analysis of 1,331 sedations using inhalation, intravenous, or other techniques.

The safety and efficacy of various sedative techniques was studied. Inhalation sedation provided the mainstay of anxiety control, whereas intravenous and combination techniques were reserved for more difficult patients or procedures. Pooled data from all techniques yielded an 87% effectiveness rate and 93% patient acceptance rate. Sedation was less often effective in persons with poorer health status than in healthy persons. Complications encountered were few, rarely of serious potential, and easily managed. Nitrous oxide sedation was effective 88.5% of the time and usually at concentrations of 50% or less. The safety and efficacy of intravenous, oral, combination, and especially inhalation sedation given by individuals not formally trained in general anesthesia appears to be confirmed. No correlation of side effects to a specific technique of administration or to patients suffering significant medical disorders could be established. However, more data need to be obtained in this area before firm conclusions can be made.

Major morbidity or mortality from office anesthetic procedures: a closed-claim analysis of 13 cases.

A closed-claim analysis of anesthetic-related deaths and permanent injuries in the dental office setting was conducted in cooperation with a leading insurer of oral and maxillofacial surgeons and dental anesthesiologists. A total of 13 cases occurring between 1974 and 1989 was included. In each case, all available records, reports, depositions, and proceedings were reviewed. The following were determined for each case: preoperative physical status of the patient, anesthetic technique used (classified as either general anesthesia or conscious sedation), probable cause of the morbid event, avoidability of the occurrence, and contributing factors important to the outcome. The majority of patients were classified as American Society of Anesthesiologists (ASA) status II or III. Most patients had preexisting conditions, such as gross obesity, cardiac disease, epilepsy, and chronic obstructive pulmonary disease, that can significantly affect anesthesia care. Hypoxia arising from airway obstruction and/or respiratory depression was the most common cause of untoward events, and most of the adverse events were determined to be avoidable. The disproportionate number of patients in this sample who were at the extremes of age and with ASA classifications below I suggests that anesthesia risk may be significantly increased in patients who fall outside the healthy, young adult category typically treated in the oral surgical/dental outpatient setting.
