ABSTRACT
Objective:To evaluate the risk factors for diaphragmatic dysfunction of patients with sepsis and septic shock, and the application value of bedside ultrasound.Methods:Patients with sepsis and septic shock in the Intensive Care Unit (ICU), General Hospital of Ningxia Medical University from January 2020 to May 2021 were prospectively recruited as the research subjects, general postoperative patients and healthy volunteers were admitted as postoperative control and normal control groups. General clinical data were collected, patients with sepsis and septic shock were dynamically observed high sensitive c-reactive protein (hs-CRP), interleukin-6 (IL-6), serum albumin, transferrin, prealbumin levels, blood lactate, Pcv-aCO 2, ScvO 2, etc.; and indirect calorimetry was used to measure the resting energy level of the patient to calculate the missing energy value. Bedside ultrasound was used to dynamically evaluate the changes of diaphragm excursion (DE),inspiratory diaphragm thickness, and expiratory diaphragm thickness, to calculate relevant parameters. DE<10 mm or diaphragmatic thickness fraction (DTF) < 20% was diagnosed as diaphragmatic dysfunction. Results:(1) On day 1 in the ICU, the DE of the septic shock group, sepsis group and postoperative control group were significantly lower than that in the normal control group [10.3 (9.0, 13.6) mm, 12.3 (9.1, 15.0) mm, 12.9 (10.5, 15.7) mm vs. 22.0 (16.0, 24.6) mm, all P<0.05], and the incidence of DTF<20% was significantly higher than in the normal control group (32.7%, 41.9%, 33.3% vs. 0 %, all P<0.05), and the incidence of DE<10 mm in the septic shock group and sepsis group was significantly higher than that of postoperative control group and normal control group (36.7%, 35.5% vs. 10.0%, 0%, respectively, all P<0.05). On day 7, the DE in the septic shock group was significantly lower than that in the sepsis group [10.5 (6.8, 13.5) mm vs. 14.4 (10.6, 18.6) mm, P<0.05].(2) Correlation analysis of each index: The DE of patients with sepsis and septic shock on day 1, 3, and 7 was negatively correlated with the hs-CRP ( r=-0.253, -0.436, -0.455, all P<0.05); On day 3, DE was also negatively correlated with IL-6 ( r=-0.338, P=0.009); and DTF was negatively correlated with hs-CRP ( r=-0.375, P=0.004). On day 1, there was a positive correlation between DTF and serum transferrin levels in patients with sepsis and septic shock ( r=0.221, P=0.049). On day 3 and 7, the DE was positively correlated with serum prealbumin levels ( r=0.318, 0.408, both P<0.05). Conclusions:Patients with sepsis and septic shock have developed diaphragmatic dysfunction on day 1 in the ICU, which is mainly manifested as decreased in diaphragm mobility and diaphragmatic thickness fraction, and is related to inflammation and high protein catabolism.
ABSTRACT
Objective To explore the early diagnosis and proper treatment for pancreas injuries. Methods 31 patients with pancreatic injury were treated from Oct. 1997 to Nov. 2008 in the Third Hospital of Yanzhou Mining Group. The early clinical signs and characters, treatment and causes of death of the 31 cases of pancreas injuries were studied retrospectively. Results All 31 cases with blunt pancreatic injury underwent operation. 28 patients were cured, 2 died from the pancreatic fistula and 1 multiple organ dysfunction syndrome.Pancreatic fistula and pancreatic pseudocysts were the main complications. Conclusions The preoperative diagnosis is difficult. Surgical exploration is the main method to guarantee accurate diagnosis of pancreatic injuries.Selecting proper surgical operation according to the situation of pancreatic injuries during the exploration can elevate successful rate.
