Effects of a Doula instrument combined with auricular acupuncture and acupoint application on numerical rating scale scores, labour time of puerperae with a natural delivery and Apgar scores of the newborns

Objective

To determine how a combination of auricular acupuncture, acupoint application and the Doula instrument affects numerical rating scale (NRS) scores, labour time of puerperae and the Apgar scores of newborns during natural delivery.

Methods

This is a retrospective study. From January 2021 to December 2022, clinical data were collected from 90 healthy primiparae who completed natural delivery at Baoding Maternal and Child Health Hospital. They were divided into two groups based on different perinatal intervention methods. While the Doula instrument was used for the control group's perinatal intervention, the study group received a combination of auricular acupuncture, acupoint application and the Doula instrument during their perinatal period.

Results

The NRS score of the study group was lower than that of the control group, demonstrating that their intergroup difference is statistically significant (P < 0.05). The incubation period, the active phase of the first stage of labour and the time of the second and third stages of work are shorter in the study group than in the control group (P < 0.05). Intergroup comparison of their one and five minutes Apgar scores demonstrates no statistically significant differences (P > 0.05). Expression levels in the study group are higher than in the control group five minutes after delivery (P < 0.05).

Conclusions

In this case, a perinatal intervention comprising auricular acupuncture, acupoint application and the Doula instrument was used for puerperae undergoing natural delivery.

Accuracy and precision of McMaster and Mini-FLOTAC egg counting techniques using egg-spiked faeces of chickens and two different flotation fluids

Faecal egg counting techniques (ECTs) are useful tools for assessing anthelmintic efficacy and selecting hosts resistant to parasite infection. McMaster (MM) is one of the most commonly used ECTs, but it suffers from low sensitivity and precision. Mini-FLOTAC (MF) has been proposed to replace MM, but so far has not been evaluated for gastro-intestinal nematode infections in chickens. This study compared sensitivity, precision, and accuracy of MM and MF with two trials using egg-spiked faecal samples ranging from 50-1250 eggs per gram of faeces (EPG). In addition, effects of two flotation fluids with different specific gravities (SG), namely salt (SG = 1.20) and sucrose solutions (SG = 1.32), on accuracy and time-spent for both ECTs were evaluated. Overall sensitivity based on the composite reads across all EPG-levels was 97.1 % for MM and 100 % for MF. MF was, however, more sensitive (P = 0.003) or tended to (P = 0.087) be more sensitive than MM at only the lowest EPG-level (i.e. 50 EPG) using one of the duplicate reads, whereas there was no significant difference at any EPG-level using composite reads. Overall average precision of MF (79.5 %) was higher (P < 0.001) than that of MM (63.4 %) across all EPG-levels. Precision of MM increased from 22 to 87 % with increasing EPG-levels from 50-1250 EPG. Corresponding precision estimates for MF ranged from 76 to 91 %. Overall recovery rate of MM (74.6 %) was significantly higher (P < 0.001) than that of MF (60.1 %). There was no significant difference in recovery rate of spiked-eggs among different EPG-levels (P = 0.833). Recovery rate of MM ranged from 64 % to 79 % across different EPG-levels, while it ranged from 54 % to 64 % with MF without an interaction between ECT and EPG-level (P = 0.701). It took more time (P < 0.001) to process (prepare and read) samples with MF than with MM using the same flotation fluid. The sugar solution tended to (P = 0.100) increase egg-recovery with both ECTs, while increasing (P < 0.001) time-spent for processing the samples. Our data collectively suggest that MM is less sensitive than MF only at around minimum detection level of MM when using unrepeated reads. We conclude that McMaster is faster, relatively more accurate but less precise than Mini-FLOTAC. The sugar solution with higher SG increases accuracy of both techniques at the expense of increased labour time.
