Positional,pressure stretch damage.The mechanism of muscle damage that occurs when patients with normal muscle have surgery for long periods in certain positions is not known precisely. However, pressure stretch damage, followed by ischaemia and reperfusion may all contribute. Large numbers of reports of rhabdomyolysis have occurred, in association with prolonged surgery in the following positions.The majority of the operations lasted in excess of 6 h and evidence of compartment syndrome could be found in the relevant muscles.
Life-threatening problems identified during the primary survey in the multiply injured patient are managed first. Only then should attention be turned to the extremity injury.The specific management of complications such as vascular injury, compartment syndrome, traumatic amputation, and open wounds have been discussed earlier in this chapter. Fractures (or suspected fractures) should be immobilised to control pain and prevent further injury. Splintage is a most effective way of controlling pain and subsequent doses of analgesia may be reduced. If pain increases after immobilisation, then an ischaemic injury and or compartment syndrome must be excluded. Emergency splinting techniques for various injured extremities are described below.
And compartment syndrome have been described in young alcoholics undergoing treatment with benzodiazepines (Rutgers et al 1991). Rhabdomyolysis and acute renal failure occurred from a beta-2 adrenoreceptor agonist terbutaline (Blake & Ryan 1989), secondary to intense beta receptor stimulation.
With infection in the anterior compartment, there is usually high fever and chills, tender swelling below the angle of the mandible, induration and erythema of the side of the neck, and trismus. Most patients are acutely ill, have odynophagia, dysphagia, and mild dyspnea. A bulge in the lateral pharyngeal wall can be observed but the tonsil is normal in size and relatively uninflamed. Torticollis toward the side of the abscess (due to muscle spasm) is found often as is cervical lymphadenitis (CL). The classical triad of pharyngomaxillary abscess occurs only in anterior compartment syndrome and includes (i) tonsillar and tonsillar fossa prolapse, (ii) trismus, and (iii) swelling of the parotid area. Infection in the posterior compartment is characterized by signs of septicemia, with minimal pain or trismus. Swelling can often be overlooked because it is deep behind the palatopharyngeal arch. Indirect laryngoscopy can reveal ipsilateral obliteration of the pyriform sinus. A tender high...
Can occur at rest (polymyositis), and may be the leading symptom in polymyalgia rheumatica. Focal muscle pain in association with exercise-induced ischemia is observed in occlusive vascular disease. Local, often severe, pain is the hallmark of a compartment syndrome occuring after exercise or ischemia. Exercise-induced muscle pain in association with muscle cramps can be seen in metabolic disease.
Rhabdomyolysis ofvarying degrees of severity can be precipitated by a wide range of conditions, including drug overdoses, and the administration of certain anaesthetic agents. It is more likely to occur when there is muscle disease, but drug overdoses may precipitate rhabdomyolysis in apparently normal muscle. However, during surgery and anaesthesia the commonest causes are compartment syndrome, secondary to pressure stretch injury during prolonged surgery in one position, tourniquet use for a long time, or at a high pressure, and reperfusion injury after acute ischaemic damage.
Potentially huge volume of fluid can enter the soft tissue before the pump stops in response to the alarm for elevated venous pressure. In many cases, the graft is unusable for weeks after such an episode. Continued use of the access in this setting may result in loss of the access site. B, In this example, the infiltration was composed of approximately 400 mL of priming crystalloid and blood, located both deep and superficial to the investing fascia of the arm. The access remained patent and was eventually restored to function however, a series of percutaneous drainage procedures and open drainage were necessary. Compartment syndrome, with loss of distal motor function or sensation in the arm, is another concern in this setting, and drainage must be performed to treat this surgical emergency.
