Comparison of the Effectiveness of Neostigmin 0.5 mg and Neostigmin 1 mg Intramuscular for Emptying of the Bladder after Spinal Anesthesia

Introduction

Neostigmin is a medication that plays a crucial role in overcoming various problems related to the accumulation of acetylcholine around the cholinergic nerve endings. This drug works by increasing the levels of acetylcholine needed for the contraction of the bladder detrusor muscle, which is very dependent on the stimulation of muscarinic receptors. In this context, this study aims to compare the effectiveness of neostigmin with a dose of 0.5 mg and 1 mg intramuscularly in accelerating the bladder emptying process after spinal anesthesia.

The Importance of Neostigmin in Clinical Practice

Neostigmin is a medication that has been widely used in clinical practice to overcome various problems related to the accumulation of acetylcholine around the cholinergic nerve endings. This drug works by increasing the levels of acetylcholine needed for the contraction of the bladder detrusor muscle, which is very dependent on the stimulation of muscarinic receptors. In this context, the use of neostigmin is essential in accelerating the bladder emptying process after spinal anesthesia.

Research Purposes

This study was conducted to find out which of the two doses of neostigmin is more effective in accelerating the emptying of the bladder after the spinal anesthesia. By using a random clinical trial, this study was conducted at the Adam Malik Medan Hajj General Hospital and Putri Hijau Hospital in Medan between December 2018 and February 2019. Through this study, it is expected to find optimal doses that can be used in clinical practice.

Methodology

Of the total samples obtained, there were 37 patients who received neostigmin 0.5 mg and 37 patients who received neostigmin 1 mg intramuscularly. The measured parameters are the volume of urine released in the initial observation (T0) and Final Observation (T5). This measurement aims to assess the effectiveness of the two doses in accelerating the emptying of the bladder.

Research Design

This study used a random clinical trial design to compare the effectiveness of neostigmin 0.5 mg and neostigmin 1 mg intramuscularly in accelerating the bladder emptying process after spinal anesthesia. The study was conducted at two hospitals in Medan, Indonesia, and involved a total of 74 patients who received either neostigmin 0.5 mg or neostigmin 1 mg intramuscularly.

Data Collection

The data collected in this study included the volume of urine released in the initial observation (T0) and Final Observation (T5). The volume of urine was measured using a catheter, and the data was recorded in a standardized format.

Data Analysis

The data was analyzed using statistical software to compare the effectiveness of neostigmin 0.5 mg and neostigmin 1 mg intramuscularly in accelerating the bladder emptying process after spinal anesthesia. The results of the analysis showed that both doses of neostigmin were effective in accelerating the bladder emptying process, but neostigmin 1 mg was more effective than neostigmin 0.5 mg.

Research Result

From the observations made, the group that received a 0.5 mg neostigmin shows the average initial urine volume of 133.51 cc and reduced to 63.51 cc in the final observation. The results of statistical analysis showed the P value of 0.000, which means there is a significant difference in the volume of urine between initial and end observations, indicating that this dose is effective.

On the other hand, groups that receive neostigmin 1 Mg also show significant results with the same P value (0,000), showing a clear difference in the speed of urinating between the two groups. Overall, the group that gets a neostigmin 1 mg has a faster work onset than the group that receives 0.5 mg.

Conclusion

From the analysis conducted, it can be concluded that neostigmin 1 mg is more effective in accelerating post-spinal bladder emptying compared to 0.5 mg neostigmin. These findings have important implications for clinical practices, especially in determining the optimal dose of neostigmin to minimize the retention of the post-spinal anesthetic procedure. Thus, this study provides valuable insight to medical personnel in managing post-anesthesia patients.

Implications for Clinical Practice

The findings of this study have important implications for clinical practices, especially in determining the optimal dose of neostigmin to minimize the retention of the post-spinal anesthetic procedure. The use of neostigmin 1 mg is recommended as the optimal dose for accelerating post-spinal bladder emptying.

Limitations of the Study

This study has several limitations, including the small sample size and the use of a random clinical trial design. Future studies should aim to replicate the findings of this study using a larger sample size and a more robust research design.

Future Directions

Future studies should aim to investigate the effectiveness of neostigmin in accelerating bladder emptying in patients with different types of anesthesia. Additionally, studies should aim to investigate the optimal dose of neostigmin for different patient populations.

Frequently Asked Questions (FAQs) about Neostigmin and Spinal Anesthesia

Q: What is neostigmin and how does it work?

A: Neostigmin is a medication that works by increasing the levels of acetylcholine needed for the contraction of the bladder detrusor muscle, which is very dependent on the stimulation of muscarinic receptors. It is used to accelerate the bladder emptying process after spinal anesthesia.

Q: What is spinal anesthesia and how does it affect the bladder?

A: Spinal anesthesia is a type of anesthesia that numbs the lower part of the body, including the bladder. This can cause the bladder to become overactive and difficult to empty, leading to urinary retention.

Q: What are the benefits of using neostigmin after spinal anesthesia?

A: The benefits of using neostigmin after spinal anesthesia include accelerating the bladder emptying process, reducing the risk of urinary retention, and improving patient comfort.

Q: What are the side effects of neostigmin?

A: The side effects of neostigmin are generally mild and temporary, and may include nausea, vomiting, and diarrhea. In rare cases, neostigmin can cause more serious side effects, such as allergic reactions and increased heart rate.

Q: How is neostigmin administered?

A: Neostigmin is typically administered intramuscularly, which means it is injected into a muscle. The dose and frequency of administration will depend on the individual patient's needs and medical history.

Q: What are the different doses of neostigmin and how do they compare?
