Background:This retrospective study examined the effectiveness and safety of polygeline in adult patients with hypovolemia due to traumatic injury.Materials and Methods:Polygeline was administered after evaluating the amount of blood loss and estimating hematological and biochemical parameters. Changes in vital signs, serum electrolytes, arterial pH, and serum lactate were evaluated. The safety was evaluated by recording the adverse events if any.Results:Sixty patients with the mean age 37.5 ± 11.26 years were included in the study. All patients had blood loss < 20%. The mean total polygeline administered was 1025.0 ± 464.18 ml. Blood transfusion was required in 3.33% of patients. Diastolic, systolic, and mean arterial blood pressure and pulse rate significantly increased after 1 h of polygeline administration (P < 0.0001). There was a trend toward increase in urine output (P = 0.0715) after 1 h. The improvement in vital parameters was consistent at 6, 14, and 18 h after administration of polygeline. Arterial pH significantly increased from 7.2 ± 0.12 to 7.3 ± 0.11 after 1 h of administration (P < 0.0001) and was consistent till 24 h (P = 0.035). Blood lactate decreased after 1 h (P < 0.0001). Changes in laboratory parameters were not clinically significant. After mean duration hospital stay of 10.5 ± 4.63 days all patients were discharged without any clinically significant abnormality or adverse event.Conclusion:Polygeline improved hemodynamic stability in patients with hypovolemia due to traumatic injury. The improvement was seen within 1 h (golden hour) of polygeline administration and maintained consistently. Polygeline can be safely administered to patients with traumatic injury to improve hemodynamic parameters and achieve stability.

Background: Objective of present study was to evaluate the safety of polygeline (Haemaccel®) and its effect on vital sign parameters in patients with hypovolemia caused by accidental trauma.Methods: Adverse drug reactions (ADRs) of polygeline within 6 hours after administration, and the effect of polygeline infusion on vital sign parameters, in trauma patients hospitalized at the emergency department, were evaluated in this prospective, multicentric, post-marketing observational study.Results: One hundred forty patients (men: 81.4%; women: 18.6%), with a mean (±standard deviation) age of 33.7±10.6 years, were enrolled. At the time of admission, mean blood volume loss was 1400.1±558.8ml, with 86.4% patients reporting blood volume loss of >15%; 49.3% patients presented with class-II hypovolemia. No ADRs or any unusual clinically significant changes were reported within 6 hours of polygeline administration. All vital parameters (blood pressure and pulse rate) significantly improved at 1 hour of polygeline administration; this trend was sustained until 6 hours (p<0.001). Reduction in respiratory rate was significant at 1 and 6 hours versus baseline (p<0.001). Urine output and central venous oxygen saturation also showed significant improvement at 1 and 6 hours after treatment initiation (p<0.001). Arterial pH and mean blood lactate levels also showed a significant change from the baseline (p<0.05) at both 1 and 6 hours.Conclusions: Polygeline was found to be safe and effective in improving hemodynamic stability in patients with hypovolemia due to accidental trauma.

Levofloxacin exhibited significant analgesic activity in a human pain model and can be used in infections associated with pain or for pre-operative prophylaxis. Further investigations are required to understand the precise mechanism and pathway of antinociception exhibited by levofloxacin.
