Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. The early mortality of patients with sepsis-induced myocardial dysfunction (SMD) is higher than those with normal cardiac function, and the long-term prognosis is worse. Therefore, early detection of SMD and timely intervention can reduce mortality and improve prognosis. This review focused on the progress in evaluation and treatment of SMD, with a view to provide some ideas for the diagnosis and treatment of SMD.

Sepsis-associated encephalopathy(SAE) caused by infections outside the central nervous system always presents extensive brain damage.It is common in clinical practice and associated with a poor prognosis.There are problems in the assessing and diagnosing of SAE.Many factors,such as sedation and mechanical ventilation,make it difficult to assess SAE,while electrophysiological examination may play a role in the assessment.We reviewed the studies of electrophysiological techniques such as electroencephalography and somatosensory evoked potentials for monitoring SAE,hoping to provide certain evidence for the clinical evaluation and diagnosis of SAE.

Sepsis induced by invasive infection is a challenging problem and the major cause of death after severe burn. With the increasing understanding of sepsis, diagnostic criteria of sepsis were proposed and revised consecutively so that they could be consistent with the clinical practice. Being different from other trauma and critical diseases, diagnostic criteria of sepsis after severe burn were also proposed, and they need further clinical verification. It is believed that comprehensive measures for the treatment of severe sepsis after burn should be advocated. These measures include rapid and effective resuscitation of burn shock, early escharotomy and closure of burn wound, metabolic support, immunoregulation and anti-inflammation, reinforcement of organ support, etc. Although a number of advances have been achieved in the past decades, the mechanism of sepsis need further elucidation, diagnostic criteria of sepsis need further revision, and novel therapeutic measures for burn sepsis should be developed.

Pediatric burn patients account for more than 1/3 of the inpatients in the same period, and its incidence surpasses that of burn patients in other age groups. However, it brings about much difficulty to treat pediatric burn patients complicated by sepsis, which brings a significantly higher mortality than that of the adult. Moreover, the physiological characteristics, development of organs, drug metabolism, and body response to burn injury in children are obviously different from those of the adult. Therefore, it is clinically important to understand the clinical characteristics of sepsis in pediatric burn patients in order to improve the diagnosis and treatment of this ailment.

OBJECTIVETo report a case of critical illness polyneuropathy (CIP) with Parkinson disease and discuss the development, clinical features and early diagnosis of this condition.

METHODSThe clinical data of a patient with CIP and Parkinson's disease and the relevant literature were reviewed.

RESULTSThis case showed no typical disease course of sepsis, and the condition exacerbated rapidly. The patient presented initially with abnormal homeostasis, followed by rapid onset of respiratory muscle weakness to require mechanical ventilation, but no limb weaknesses were detected. Intravenous antibiotics and aggressive treatment of sepsis did not produce any positive responses to wean from mechanical ventilation. Examinations of creatine kinase and cerebrospinal fluid showed no abnormalities. Electromyography and nerve conduction studies demonstrated declined nerve conduction velocity and decreased sensory and motor muscle action potentials, suggesting the possibility of CIP.

CONCLUSIONIn patients with Parkinson disease, the occurrence of sepsis with prolonged mechanical ventilation and limb weakness indicates the necessity of neurophysiological examination, muscle biopsies and laboratory tests, which may help detect CIP in the early phase. Proper interventions of sepsis may reduce the likeliness of CIP. Elimination of the risk factors and aggressive management of sepsis can be effective measures for preventing CIP.

OBJECTIVEThe objective was to evaluate the protective effects of dexmedetomidine (DEX), a selective agonist of α2-adrenergic receptor, on sepsis-induced diaphragm injury and the underlying molecular mechanisms.

DATA SOURCESThe data used in this review were mainly from PubMed articles published in English from 1990 to 2015.

STUDY SELECTIONClinical or basic research articles were selected mainly according to their level of relevance to this topic.

RESULTSSepsis could induce severe diaphragm dysfunction and exacerbate respiratory weakness. The mechanism of sepsis-induced diaphragm injury includes the increased inflammatory cytokines and excessive oxidative stress and superfluous production of nitric oxide (NO). DEX can reduce inflammatory cytokines, inhibit nuclear factor-kappaB signaling pathways, suppress the activation of caspase-3, furthermore decrease oxidative stress and inhibit NO synthase. On the basis of these mechanisms, DEX may result in a shorter period of mechanical ventilation in septic patients in clinical practice.

CONCLUSIONSBased on this current available evidence, DEX may produce extra protective effects on sepsis-induced diaphragm injury. Further direct evidence and more specific studies are still required to confirm these beneficial effects.
