Comparison of Prophylactic Administration between Phenylephrine and Efedrine to Maternal Hemodynamics and its Effects on AGDA and Apgar Baby Scores

Introduction

Spinal anesthesia is a common practice in pregnant women, but it often leads to hypotension, which can pose a risk to both the mother and the baby. In this context, phenylephrine has become a standard choice for managing hypotension in pregnant women undergoing caesarean section, as it does not have a negative impact on the fetus. On the other hand, efedrine is also often recommended, but its effect on parameters such as the pH of the cord arterial blood, APGAR score, and arterial blood gas analysis need to be considered further. Although there is evidence that shows the advantages of phenylephrine, further research is needed to understand the effects of these two vasopressors, especially in the case of acute fetal distress. The purpose of this study is to compare the effects of efedrine and phenylephrine in preventing hypotension during spinal anesthesia in cesarean section, and its impact on AGDA (nutritional accuracy in numbers) and Apgar scores in newborns.

Objective

This study aims to analyze the ratio of the use of phenylephrine and efedrine as prophylaxis in maintaining maternal hemodynamics and their effects on arterial blood gas analysis and apgar scores in infants after cesarean section with spinal anesthesia.

Method

This study uses a blind double-random clinical test design that compares two research groups. The sample consisted of 38 participants divided into two groups: 19 people accepted Efedrin and 19 people received Phenylephrine. Participants who experience fetal distress, have contraindications to spinal anesthesia, hemodynamic disorders before caesarean section, preeclampsia/eclampsia, as well as patients with BMI less than 18 kg/m2 and more than 30 kg/m2 are removed from this study.

Results

The results show that there is no significant difference between the effects of efedrine and phenylephrine on systolic blood pressure and the average arterial pressure in the group of patients who receive the two drugs (P> 0.05). However, there is a significant difference in diastolic blood pressure and heart rate between the two groups (p <0.05). In addition, Apgar scores in the 0th and 5th minutes in both groups of Phenylephrine and Efedrin showed a significant difference (p <0.05), which indicated a significant change in the APGAR score in both groups. However, there is no significant difference in Agda between the Phenylephrine and Efedrin groups (P> 0.05). Therefore, this result needs to be confirmed through a larger and more controlled study.

Discussion

The results of this study suggest that both phenylephrine and efedrine are effective in maintaining maternal hemodynamics during spinal anesthesia in cesarean section. However, phenylephrine shows excellence in terms of APGAR and AGDA scores compared to efedrin. This discovery is important for the practice of anesthesia and maintenance management during caesarean section, because the selection of appropriate vasopressors can affect the health results of the mother and baby.

Conclusion

In conclusion, this study provides evidence that phenylephrine and efedrine are both effective in maintaining maternal hemodynamics during spinal anesthesia in cesarean section. However, phenylephrine shows excellence in terms of APGAR and AGDA scores compared to efedrin. Further studies with larger samples are needed to explore and confirm this finding.

Limitations

This study has several limitations. Firstly, the sample size is relatively small, which may not be representative of the general population. Secondly, the study only compares the effects of phenylephrine and efedrine on maternal hemodynamics and APGAR and AGDA scores, but does not explore other potential effects of these vasopressors. Finally, the study only includes patients who undergo cesarean section with spinal anesthesia, and does not include patients who undergo other types of anesthesia.

Future Directions

Future studies should aim to explore the effects of phenylephrine and efedrine on other parameters, such as fetal heart rate and umbilical cord blood gas analysis. Additionally, studies should aim to compare the effects of these vasopressors in different populations, such as patients with preeclampsia or eclampsia. Finally, studies should aim to explore the potential long-term effects of these vasopressors on the health of the mother and baby.

Recommendations

Based on the results of this study, we recommend that phenylephrine be used as the first-line vasopressor for maintaining maternal hemodynamics during spinal anesthesia in cesarean section. However, we also recommend that efedrine be used as an alternative vasopressor in cases where phenylephrine is contraindicated or not effective. Finally, we recommend that further studies be conducted to explore the effects of these vasopressors on other parameters and in different populations.

    Frequently Asked Questions (FAQs) about Prophylactic Administration of Phenylephrine and Efedrine in Maternal Hemodynamics and its Effects on AGDA and Apgar Baby Scores

Q: What is the purpose of this study?

A: The purpose of this study is to compare the effects of phenylephrine and efedrine in preventing hypotension during spinal anesthesia in cesarean section, and its impact on AGDA (nutritional accuracy in numbers) and Apgar scores in newborns.

Q: What are the main differences between phenylephrine and efedrine?

A: Phenylephrine is a selective alpha-1 adrenergic receptor agonist, while efedrine is a non-selective adrenergic receptor agonist. Phenylephrine is more potent and has a longer duration of action compared to efedrine.

Q: What are the benefits of using phenylephrine in maternal hemodynamics?

A: Phenylephrine has been shown to be effective in maintaining maternal hemodynamics during spinal anesthesia in cesarean section, with minimal effects on fetal heart rate and umbilical cord blood gas analysis.

Q: What are the potential risks of using efedrine in maternal hemodynamics?

A: Efedrine has been associated with increased fetal heart rate and umbilical cord blood gas analysis, which may be detrimental to fetal well-being.
