ABSTRACT
Objective To compare the effect of 0.9％ NaCl solution, Ringer solution, and acetate sodium potassium magnesium calcium glucose solution (ASPMCG solution) on internal environment in patients with septic shock receiving early fluid resuscitation.Methods A prospective randomized controlled trial was conducted. From June 2016 to January 2018, a total of 280 patients with septic shock admitted to intensive care unit (ICU) of Northern Jiangsu People's Hospital were enrolled. All eligible patients were randomly divided into 0.9％ NaCl solution group (group N), Ringer solution group (group L) and ASPMCG solution group (group P) with random number table. In all patients, catheters were placed in the right internal jugular vein or subclavian vein and were infused with 30 mL/kg of corresponding crystalloid within 3 hours after admission. According to fluid responsiveness, the rehydration rate and fluid volume were determined by the researcher within 6 hours. Other treatments were based on the 2012 Surviving Sepsis Campaign (SSC) guidelines during the study. In this study, 6-hour or 24-hour fluid volume and 7-day exogenous insulin use were recorded. The changes in arterial blood pH, base excess (BE), blood glucose (Glu), lactic acid (Lac), and serum Na+, K+, Cl-, Ca2+ were observed at 0, 3, 6, 24 hours, and 3 days and 7 days of resuscitation.Results In this study, a total of 1082 patients were admitted to the ICU, and patients who did not meet the diagnostic criteria for septic shock, death or discharge within 24 hours of ICU admission were excluded. Finally, 280 patients with septic shock were enrolled in the analysis, with 94 patients in group N, 94 patients in group L and 92 patients in group P.

Finally, 280 patients with septic shock were enrolled in the analysis, with 94 patients in group N, 94 patients in group L and 92 patients in group P. There was no significant difference in the amount of crystalloid, colloidal fluid, total fluid within 6 hours or 24 hours or exogenous insulin dose within 7 days among the three groups. After fluid resuscitation, blood Cl- concentration in the three groups was increased in different degrees, peaked at 24 hours, but it in group N was significantly higher than that in group L and group P (mmol/L: 107.5±5.6 vs. 106.1±4.8, 105.1±4.2, bothP ﹤ 0.05). Moreover, blood Ca2+concentration also showed an increased tendency, it was significantly lower at 3 hours and 6 hours in group N than that in group L and group P (mmol/L: 1.10±0.08 vs. 1.15±0.09, 1.12±0.10 at 3 hours, 1.12±0.10 vs. 1.16±0.08, 1.15±0.09 at 6 hours, all P < 0.05). There was no significant difference in blood Cl- or Ca2+between groups L and P (bothP > 0.05). Arterial blood pH, BE, Glu, Lac, Na+, or K+at each time point during fluid resuscitation also showed no difference among the three groups.Conclusion Among patients with septic shock receiving early fluid resuscitation, compared with Ringer solution and ASPMCG solution, 0.9％ NaCl solution may cause hyperchloremia and hypocalcemia, but has no significant effect on acid-base balance.Clinical Trial Registration Chinese Clinical Trial Registry, ChiCTR-IOR-16009176.
ABSTRACT
BACKGROUND: After induction of anesthesia with propofol or thiopental, rocuronium causes hand or limb withdrawal or generalized movements, suggesting the presence of intense pain even under anaesthesia. We evaluated the effect of diluting rocuronium 10 mg/ml solution to 5 mg/ml or 3.3 mg/ml with 0.9% NaCl solution on the withdrawal movements associated with IV administration of rocuronium given at intubating doses after thiopental administration. METHODS: Sixty three patients undergoing surgical procedures that required general anesthesia were randomized into three groups. Group 1 received rocuronium 0.9 mg/kg in 10 mg/ml solution, while Group 2 and 3 received the same dose of rocuronium in 5 mg/ml and 3.3 mg/ml solutions with 0.9% NaCl solution after thiopental IV administration, respectively. RESULTS: We observed that the incidence of withdrawal movements was 71.4% in the Group 1, 47.6% in the Group 2 and 14.3% in the Group 3. Intense withdrawal movements involving elbow or shoulder and generalized movements were observed in 42.8% of patients in Group 1, but they were seen in 23.8% of patients in Group 2 and 4.8% of patients in Group 3. There were significant differences in incidence and degree of withdrawal movements between Group 1 and 3 (P < 0.05). The pH values and osmolalities of study solutions were not significantly different between the groups. CONCLUSIONS: Dilution of rocuronium with 0.9% NaCl solution given at intubating doses after thiopental administration is a simple and cost-effective strategy for preventing withdrawal movements during IV rocuronium injection.
