Brief Summary

Antimicrobial and supportive therapeutic interventions in patients with septic shock are usually effective - procalcitonin and interleukin-6 levels fall rapidly in most cases, and noradrenaline support can be discontinued within a few days. Unfortunately, only in a small portion of patients, do the organ functions improve at the same time, and in most of them, multi-organ failure persists. Therefore, it is likely that, in addition to infection and the response to infection, other mechanisms are also involved in the persistence of organ failure in patients after septic shock.

Detailed Description

One of the possible explanations for prolonged multi-organ dysfunction after an excessive inflammatory phase is a disorder of "post-inflammatory cleaning", the so-called resolution of inflammation. The resolution of inflammation is a regulated process in which the controlling action of specialized pro-resolution mediators (lipoxins, resolvins, etc.), conversion of pro-inflammatory macrophages (M1) to pro-resolution (M2., induce the process of structural tissue restoration), autophagy plays a significant role and, of course, the flushing of accumulated interstitial fluid with waste products by lymphatic drainage. Any disturbance in pro-resolution mechanisms can lead to prolonged organ dysfunction.

The lymphatic system plays a key role in maintaining fluid homeostasis. Its ability to drain interstitial fluid can increase up to 20 times. However, even such an increase may not be sufficient in the situation of extreme interstitial fluid sequestration that accompanies septic shock. In addition, some inflammatory mediators (for example, nitric oxide, TNF-α, Interleukin-1β) cause relaxation of the vascular structures of the lymphatic system, slowing the flow of lymph. The result is the persistence of tissue swelling with tissue hypoxia due to the extension of the diffusion path for oxygen and the accumulation of waste products of inflammation.

Manual lymphatic drainage (MLD) is one of the treatments that stimulate the lymphatic system. In general, it is expected to accelerate the outflow of lymph and waste products from tissues previously affected by inflammation, accelerate the recovery of tissue function, sympatholytic effect and increase the tension of the vagus nerve. It can therefore be assumed that MLD will have a beneficial effect on the course of persistent multi-organ dysfunction in patients after therapeutically managed septic shock.
