A case of Mendelson's syndrome during induction of anesthesia has been reported. The patient was treated with hydrocortisone IV, oxygen c IPPB, aminophylline and antibiotics. The patient recovered completely 3 days after aspiration. We must take the preventive measure for aspiration into the lung during anesthesia, especially obstetric patient.

Extravasation necrosis due to intravenously administered fluids and drugs is an increasing problem in hospital practice. The incidence of extravasation is variable but skin necrosis is a potentially devastating complication of intravenous therapy. Local injection of hyaluronidase has been recommended for several types of infusion extravasations. The previous studies found hyaluronidase to be effective in the prevention of necrosis following intradermal nafcillin, 12% dextrose, sodium bicarbonate, aminophylline or vince alkaloids.The objectives of the study are to determine the dosage of hyaluronidase which is effective in reducing extravasation necrosis caused by 10% calcium-gluconate and to establish how soon after this extravasation it must be given to retain its effectiveness.Study I evaluated control versus only normal saline group and normal saline with hyaluronidase groups (dose:75,150,300,450 units; all in volume 2 ml, treatment delay:immediate, 15-minutes delay, half hour delay, one hour delay, three hour delay). Size and rate of eschar were compared between groups. Study II was undertaken to examine the evolution of calcium-gluconate induced soft tissue injury in the rabbit. The histologic findings of extravasation sites were compared between groups. A statistically significant protective effect was found in the treated group versus the nontreated group within 15 minutes to 30 minutes. The most effective protection was achieved by the immediate injection of 300 units dosage of hyaluronidase.In conclusion, in the 10% calcium gluconate-induced extravasation, the given data suggest that one can expect the most protective effect with a 300 units dosage of hyaluronidase and within half-hour delay in the treatment group.

OBJECTIVETo study the pharmacokinetic and pharmacodynamic features of different doses of aminophylline in very low birth weight (VLBW) infants with different postmenstrual ages, weights, and ages (in days).

METHODSA total of 40 VLBW infants with apnea were enrolled. After an intravenous loading dose of 5 mg/kg aminophylline, they were randomized into two groups with different maintenance doses of aminophylline (1 mg/kg and 2 mg/kg, once every 8 hours). Blood concentrations of aminophylline and liver and renal functions were monitored at 8 hours, 3 days, and 7 days after the loading dose. Attacks of apnea were documented. Pharmacokinetic data of aminophylline were compared between the two groups.

RESULTSThe steady-state plasma concentration of aminophylline and plasma clearance in the 2 mg/kg group were significantly higher than those in the 1 mg/kg group (P<0.05). However, the elimination half life was shorter in the 2 mg/kg group (P<0.05). Days of apnea attacks within 7 days after birth in the 2 mg/kg group were significantly fewer than in the 1 mg/kg group (P<0.05). Aminophylline plasma clearance was positively correlated with age (in days) after birth and postmenstrual age in both groups.

CONCLUSIONSIn VLBW infants, pharmacokinetics and pharmacodynamics are different when different maintenance doses of aminophylline are given. The maintenance dose of 2 mg/kg is associated with a better effect in the treatment of apnea. Postmenstrual age and age (in days) should be considered during the adjustment of dose, and routine blood concentration monitoring should be performed.

PURPOSE: Some patients develop side effects from theophylline even at low serum concentrations. We designed a prospective study to evaluate the side effects of theophylline. METHODS: A Prospective, controlled trial study was conducted. The low-dose group received an intravenous continuous aminophylline dose of 5 mg/kg/day on the first day and subsequently 10 mg/kg/day on the following two days. The usual-dose group received 10 mg/kg/day for three days and the control group received normal saline for three days. Heart rate, respiratory rate, serum concentration of theophylline, and four adverse events (irritability, sleep disturbance, jitter, and vomiting) were checked at the time of admission and at 2, 12, 24, 48, and 72 h after the start of aminophylline infusions. RESULTS: Nine patients out of 37 in the low-dose group and six of 21 in the usual-dose group dropped out because of uncontrolled irritability. The serum concentrations of theophylline in dropouts (3.68+/-1.93 ig/mL) and participants (4.47+/-2.45 ig/mL) were not significantly different. Irritability was a more frequent side effect in the usual-dose group at 12 h, but there was no difference between the low-dose and usual-dose groups in terms of vomiting, sleep disturbance, and jitter. Most of the severe adverse effects were observed in children below two years of age. CONCLUSION: Some patients dropped out regardless of the initiating aminophylline dose, especially patients under the age of two years.

Mesotherapy is a widely used technique of intradermal or subcutaneous microinjection of a drug or cocktail of drugs, at sites of the body with medical or aesthetic problems. Rare cutaneous side effects have been previously reported, including allergic reactions to the administered drugs or skin infections. We herein report a case of an immediate adverse reaction following mesotherapy. A 40-year-old woman was referred to our department with pruritic erythematous urticarial plaques at the sites of application of mesotherapy. She had been treated for abdominal liposis with one session of multiple subcutaneous injections of a drug mixture including aminophylline at a local clinic. After clinical recovery, a skin test using the same drugs was performed. A positive intradermal test was found with aminophylline and ethylenediamine that is an ingredient of aminophylline. These results support that the ethylenediamine component of aminophylline is identified as the etiologic agent.

A concern about drug therapy for obesity has been increased with launching of new anti-obesity drug in Korea. Subcutaneous injection of aminophylline was used for regional lipolysis, but its effectiveness and safety are controversial. The purpose of this study is to investigate the effects of aminophylline on lipolytic activity and cytotoxic effect in adipocytes. Preadipocytes obtained from human breast fat tissue were cultured in monolayer culture system. Cells were treated with media added 1, 5, 10, 15, 25 mM aminophylline concentrations, respectively. Cytotoxicity was measured by XTT colorimetric assay and cell count. The lipolytic activity was measured by enzymatic autoanalyzed system. At above 15mM of aminophylline concentration, preadipocyte and adipocyte markedly presented cytotoxic effects. In proportion to concentration, lipolytic activity was increased and maximal lipolytic activity without marked cytotoxicity was measured at 10mM of aminophylline concentration.

The obesity induce not only physical problem, but psychological and emotional problem. The focus of body contour procedures is the body's unequal distribution of fat. Aminophylline is a 2-adrenaline agonist, an adenosine inhibitor, and a phosphodiesterase inhibitor. It activates c-AMP, and facilitates lipolysis. Forty rats were used to study the effect of aminophylline subcutaneous injection, and divided in four groups, In the control group(n=10), saline was injected to subcutaneous fat of the abdomen. In the experimental group, aminophylline 50 mg/kg(n=10), 100 mg/kg(n=10) and 200 mg/kg(n=10) were injected. The injection was done daily for three weeks. The four groups were measured by weight, abdomen circumference, biochemistry, and histopathological test. There were no difference among the four groups. In conclusion, aminophylline subcutaneous injection is not effective in the reduction of regional and systemic fat.
