However, scholars have seldom carried out continuous empirical study on the extent of such contribution mainly due to limited methods for the calculation of labor allocation effect. This paper employs the incremental analysis method of index to separate labor allocation effect from economic growth in order to conduct an analysis on such effect under the framework of economic growth. Using this approach, this paper has calculated the labor allocation effect during various periods of time in China between 1978 and 2014 and the results indicate that the flow and migration of labor constituted the major source of China's economic growth during the periods between 1978 and 1987, between 1992 and 1998 and between 2003 and 2014 and still have great potentials in the coming decade. After 2025, the labor allocation effect will diminish and is likely to become a factor that hinders economic growth.展开更多

The objective is to audit the use of uterotonics in the active management of the third and fourth stages of labor. Methods: Personal data, diagnostic clinical information, blood loss and uterotonics administered were extracted from a cohort of 634 consecutive parturient. Trend in Shock Index (Pulse Rate/Systolic Blood Pressure) and 48 hours hematocrit changes were computed and analyzed. Results: There were 422 vagina deliveries and 212 caesarean sections. Primiparous mothers were 141 (34.2%), while grand multiparous mothers were 14 (3.4%). The mean visually estimated postpartum blood loss 165.9 ± 80 ml. There was no significant difference in the mean blood loss between the three parity groups of parturient [P = 0.09]. Fourteen parturient (3.44%) had blood loss ≥500 ml. The value of Shock Index (Pulse Rate/Systolic Blood Pressure) in the study ranged between 0.43 and 1.38. Logistic regression analysis of the variables associated with the switch between the three regimens of uterotonic drugs, showed a significant positive correlation between VEBL and uterotonic drugs administered [Pearson correlation = 0.130, P-value = 0.008]. In addition, there was a significant negative correlation between uterotonic drugs administered and Shock Index at 30 minutes and 2 hours postpartum. The correlation coefficient between VEBL and regimens of uterotonic drugs used was positive and significant (P = 0.019). Conclusion: Visually estimated blood loss, with shock are the main Triggers involved in switching between uterotonic drugs regimens used in active management of PPH. Shock index calculation is vital in management decision. We advocate training of all birth attendants on VEBL.展开更多
