Anesthesia for facial surgery.

We describe a reliable, simple, and safe method of monitored anesthesia care, with local anesthesia, which was used for 4500 patients undergoing facial rejuvenation procedure, without major complications and with minor side effects. All procedures were performed in a setup of a private clinic not affiliated with any hospital. The disadvantages of general anesthesia were avoided. Using careful monitoring and drug titration, even aged patients with medical problems, can benefit from this method. We are using classical, inexpensive, and safe compounds, which cope with all goals of anesthesia for aesthetic facial surgery.

Aloe vera gel hindered wound healing of experimental second-degree burns: a quantitative controlled study.

In the present study, Aloe vera gel (AVG) was applied to experimental second-degree burns in guinea pigs, and its effects on epithelialization, wound contraction, newly formed granulation tissue, and regeneration of hair follicles was compared with that effected by 1% silver sulfadiazine cream (AgSD). Epithelialization (%mean +/- SEM) on postburn day 8, 16, and 24 of the AVG-treated wounds was 38.72% +/- 2.71%, 60.34% +/- 3.28%, and 92.46% +/- 2.26%, respectively, while that of the AgSD-treated burns was 53.35% +/- 2.65%, 94.84% +/- 2.65%, and 100%, respectively (P less than .001). Contraction of the AVG-wounds was significantly higher than that of the AgSD-treated burns during 24 days of the study (P less than .001). The thickness of the newly formed granulation tissue was higher in the AVG-treated wounds (P less than .001), while the hair follicles count was significantly lower (P less than .001) compared with the AgSD-treated burns. It is concluded that this preparation of Aloe vera gel hindered the healing process of the present burn wound model when compared with 1% silver sulfadiazine cream.

Phosphorus burns: a practical approach to local treatment.

Most phosphorus burns are of limited extent. First aid consists of vigorous irrigation with water or saline followed by application of soaked dressings. At the Rambam Medical Center Burn Unit, washing of the wounds with 1% copper sulfate and 5% sodium bicarbonate solutions occurs before removal of phosphorus particles. In selected patients, prompt excision of the injured tissue and skin grafting are recommended. Fluid replacement and close monitoring of ECG, serum calcium, phosphorus, and electrolytes are recommended for all patients with such burns.
