The alarming trend of substance abuse in anesthesia providers.

The role of the anesthesia provider requires a high level of awareness and constant vigilance. Literature indicates, however, that the substance abuse rate in certified registered nurse anesthetists (CRNAs) and anesthesiologists has reached staggering levels. The literature also shows that there has been a change in which controlled drugs are being misused. It is imperative that perianesthesia nurses be aware of the current problem and take steps when indicated to protect both providers and patients. This article discusses the current trends of addiction in anesthesia providers, treatment, and reentry, as well as the role of the perianesthesia nurse in recognizing, reporting, and preventing substance abuse.     

Comparative study of the effectiveness of cefixime and penicillin V for the treatment of streptococcal pharyngitis in children and adolescents.

An open label randomized trial conducted in rural Kentucky compared the efficacy and safety of cefixime (CFX), 8 mg/kg once daily, with those of penicillin V (PEN), 250 mg 3 times daily, in 110 pediatric patients with Group A beta-hemolytic streptococcal pharyngitis. Forty-eight CFX and 47 PEN patients were evaluable for efficacy. At the end of therapy bacteriologic eradication was 45 of 48 (94%) and 36 of 47 (77%) in the CFX and PEN V groups, respectively (P < 0.05). Up to 6 weeks posttherapy 10 (21%) CFX patients and 21 (45%) PEN patients had positive Group A beta-hemolytic Streptococcus cultures (P < 0.05). Concordant serotypes were identified from 4 of 7 CFX and 15 of 17 PEN patients with positive repeat cultures. All discordant serotypes (5 of 31) were identified at greater than 19 days posttherapy. Symptomatic treatment failures (concordant serotypes) occurred in 1 (2%) CFX and 8 (17%) PEN patients (P < 0.05). Drug-related adverse experiences consisted of 2 cases of mild diarrhea and loose stools in the CFX group and none in the PEN group. No clinically significant laboratory test abnormalities occurred in either group. CFX, once daily, was as safe as and significantly more effective than PEN given 3 times daily for the treatment of Group A beta-hemolytic streptococcal pharyngitis.     

Rupture of the posterior tibial tendon: CT and surgical findings

Computed tomography (CT) was performed in 42 patients with 49 clinically suspected tears of the posterior tibial tendon. Twenty-eight of the 49 suspected tears were subsequently surgically explored and repaired. Three patterns of tendon abnormalities were recognized on CT scans: type I-intact, hypertrophied, heterogeneous tendon; type II-attenuated tendon; and type III-absence of a portion of a tendon. Types I and II correlated with partial rupture seen during surgery, and type III correlated with complete rupture of the tendon. CT findings were accurate in 96% of the patients who underwent surgery. In four cases (14%), tendon rupture was seen on CT scans, but the extent of the injury was underestimated and the rupture was misclassified. Reactive periostitis of the distal tibia was seen in 71% of diseased tendons and may represent an important factor in the diagnosis of tendon rupture.     

Nonimmune hydrops caused by massive fetomaternal hemorrhage and treated by intravascular transfusion.

Fetal hydrops at 26 weeks' gestation was diagnosed following a massive fetomaternal hemorrhage. Fetal intravascular transfusion was performed, and the hydrops completely resolved within 72 hours. The fetus required one more transfusion at 27 weeks' gestation. A subsequent percutaneous umbilical blood sampling at 30 weeks' gestation demonstrated a normal fetal hematocrit. A vaginal delivery at term resulted in a normal newborn. Massive fetomaternal hemorrhage is a well-known cause of nonimmune hydrops and may occur spontaneously in an otherwise normal pregnancy. Confirmation by percutaneous umbilical blood sampling and treatment by intravascular transfusion is recommended when massive fetomaternal hemorrhage causes hydrops in preterm gestations.
