Hypokalemia can also result from massive blood transfusion due to re- entry of potassium into RBCs and other cells during stress generic 1 mg amaryl overnight delivery, alkalosis buy amaryl 1 mg online, or massive catecholamine release associated with large volume blood loss. Therefore, potas- sium levels should be monitored routinely during large-volume blood transfu- sions. During the storage of whole blood, an acidic environment occurs due to the accumulation of lactate and citrate with a pH in the range of 6. Rapid transfusion of this acidic fluid can contribute to the metabolic acidosis observed during massive blood transfusion. However, metabolic acidosis in this setting is more commonly due to relative tissue hypoxia and anaerobic metabolism due to an imbalance of oxygen consumption and delivery. The anaerobic metabolism that occurs during states of hypovolemia and poor tissue perfusion results in lactic acidosis. The re-establishment of tissue perfusion and homeostasis is a much more important factor in re-establishing acid–base balance. In contrast, many patients receiving massive blood transfusion will experi- ence a metabolic alkalosis during the posttransfusion phase. This is due to the conversion of citrate to sodium bicarbonate by the liver and is an additional reason to avoid sodium bicarbonate administration during massive blood transfu- sion, except in cases of severe metabolic acidosis (base deficit 12). Rapid infusion of large volumes of cold (4 C) blood can result in significant hypothermia. When added to the already impaired thermoregulatory mechanisms in burn patients, this can result in significant hypothermia. Potential complications Anesthesia 131 of hypothermia include altered citrate metabolism, coagulopathy, and cardiac dysfunction. During large-volume blood transfusion in burn patients, fluids should be actively warmed with systems designed to warm large volumes of rapidly transfused blood effectively.

The primary objective of surgical treatment of burn patients is to increase survival amaryl 2 mg generic. However buy amaryl 4mg without prescription, surgery is also necessary to achieve a greater degree of func- tionality of the burned areas, which has a considerable effect on the patient’s life 257 258 Go´mez-Cıa´ and Ortega-Martınez´. Furthermore, burn surgery reduces treatment costs by reducing patients’ length of hospital stay and the number of complications and sequelae. TOPICAL TREATMENT After stabilizing the patient correctly and diagnosing the extent and depth of the wounds and associated lesions, trauma, smoke inhalation, and other factors, we begin treatment with intravenous fluids. Our overall objective is to achieve perma- nent coverage of the burns as quickly as possible. Topical treatment of burned hands is similar to that of the the rest of the body. The first step is to eliminate the causative agent, dissipate the heat, and reduce the temperature of the tissues in the first moments after the accident (cooling also re- duces inflammation and relieves pain). This can be done by profusely flushing the burns (which is especially important with chemical burns), or removing the patient from contact with an electrical source. Local treatment of burns continues with the elimination of devitalized superficial tissue, such as blisters on the hands that have ruptured. Although there is controversy over the subject, we closely evaluate the evolution of blisters that have not ruptured, watching for secondary ruptures, symp- toms of a secondary infection, or a delay in epithelialization, which would indicate a deep full-thickness burn. Once the patient is under analgesia, the wounds are pro- fusely washed with a chlorhexidine gluconate soap. When there is a loss of epithe- lium, they are covered with a petrolatum-impregnated gauze and absorbent dress- ing. Each injured finger is bandaged individually, to allow greater mobility. When a topical antiseptic is necessary we prefer 1% silver sulfadiazine, which is effective against gram-positive and gram-negative bacteria, including Pseudomonas spp. Mafenide acetate is not available for clinical use in Spain, nor are silver nitrate solu- tions used commonly. Full-thickness circumferential burns, especially those on the upper limbs, can cause compartment syndrome, which should be actively watched for in the initial hours following the accident with every change of dressing.

Temporal, but not spatial reversed in walking and running: about 60% and 40% parameters can be measured with footswitches (on/off respectively for walking and about 40% and 60%, devices detecting foot contact timing). During walking, at least one foot is walking speed, each double-limb support time com- always on the ground while during the majority of run- prises approximately 10% of the gait cycle while ning neither foot is in contact with the ground. Typical walking has two double-support phases, running has values (Kerrigan and Edelstein, 2001) of temporal gait two phases of double float during the swing period. For each condition, the bar graph begins at initial contact on the left and represents two com- plete gait cycles or strides. Note that as speed increases, time spent in swing (clear) increases, stance time (shaded) decreases, double float increases, and cycle time shortens (From Novacheck, 1998).
