Study summary

This prospective, randomized, controlled study aims to evaluate the impact of different doses of nalbuphine on anxiety and depression in patients undergoing surgery for ectopic pregnancy. Ectopic pregnancy, which occurs in approximately 2% of all pregnancies, often requires surgical intervention, leading to potential psychological distress such as anxiety and depression in affected women. Effective postoperative pain management is essential to enhance recovery and reduce emotional disturbances.

The study will involve 165 eligible patients diagnosed with ectopic pregnancy at Jinjiang District Maternal and Child Health Hospital. Participants will be randomly assigned to three groups, each receiving a different concentration of nalbuphine combined with metoclopramide for postoperative analgesia. The primary outcome will focus on changes in anxiety and depression scores measured on postoperative day three, while secondary outcomes will assess pain levels, the use of patient-controlled analgesia (PCA), the necessity for rescue analgesics, and the occurrence of adverse reactions.

Sample size calculations suggest that at least 165 participants are required to achieve adequate statistical power. Data will be analyzed using SPSS 25.0 software, with results expected to provide insights into the effectiveness of nalbuphine in improving postoperative recovery and mental health in women experiencing ectopic pregnancy. The study has received ethical approval and is funded by the Chengdu Medical Research Projects (No. 2023465, 2022548, and 2023304).

Read the detailed description

Background:

Ectopic pregnancy occurs when a fertilized egg implants outside the uterine cavity, affecting approximately 2% of all pregnancies. Surgical intervention is the primary treatment, which can lead to significant psychological effects, including anxiety and depression. Studies indicate that patients may experience various emotional disturbances post-surgery, negatively impacting their social adaptability and interpersonal relationships. Effective postoperative pain management is crucial for recovery and may also help alleviate these emotional challenges. Nalbuphine, an opioid receptor agonist-antagonist that primarily acts on the kappa receptor, has been shown to provide pain relief with a lower incidence of respiratory depression and may have a positive impact on mental health compared to traditional opioids.

Objective:

The main objective is to investigate the effects of different concentrations of nalbuphine on anxiety and depression in patients with ectopic pregnancy post-surgery, focusing on changes in anxiety and depression scores on postoperative day three. The secondary objective is to compare the postoperative analgesic effects and the incidence of adverse reactions associated with different concentrations of nalbuphine.

Methods:

This study is designed as a single-center, prospective, randomized, controlled clinical trial conducted at Jinjiang District Maternal and Child Health Hospital. Ethical approval will be obtained, and all participants will provide informed consent.

Interventions:

165 eligible patients will be randomly assigned into three groups (N1, N2, N3), each receiving different doses of nalbuphine combined with metoclopramide for postoperative pain management, with a total volume of 150ml for each group. The groups are as follows:

  • Group A: Nalbuphine 0.20 mg/ml (total 30 mg)
  • Group B: Nalbuphine 0.27 mg/ml (total 40 mg)
  • Group C: Nalbuphine 0.33 mg/ml (total 50 mg)

Patient-controlled analgesia (PCA) will be maintained for 48 hours.

Primary Outcome:

The primary outcome will be the assessment of anxiety and depression scores measured on postoperative day three.

Secondary Outcomes:

Secondary outcomes will include:

  1. Visual Analog Scale (VAS) resting and activity pain scores at multiple time points (T1: 6 hours, T2: 12 hours, T3: 24 hours, T4: 48 hours).
  2. Number of PCA button presses.
  3. Use and frequency of rescue analgesics.
  4. Incidence of adverse reactions such as drowsiness, dizziness, nausea, vomiting, and respiratory depression.
  5. Time to mobilization and time to first flatus.

Ethics Approval:

This study has received approval from the ethics committee of Chengdu Jinjiang District Maternal and Child Health Hospital (Approval Number: 202312). All participants must sign an informed consent form to ensure the respect of participant rights and data confidentiality. The study will strictly adhere to relevant ethical standards and legal regulations to protect participant safety and privacy.

What researchers measure

Primary outcomes

  1. Postoperative Anxiety and Depression Scores

    The primary outcome of this study is to evaluate the levels of anxiety and depression in patients following surgery for ectopic pregnancy. This will be assessed using the Hospital Anxiety and Depression Scale (HADS) at the following specific time point:

    Time frame: Day 3 post-surgery

Secondary outcomes

  1. Visual Analog Scale (VAS) Pain Scores

    This study will utilize the Visual Analog Scale (VAS) to assess pain levels in patients both at rest and during activity. Pain scores will be measured at the following specific time points to evaluate the efficacy of different dosages of nalbuphine in managing postoperative pain: T1: 6 hours post-surgery T2: 12 hours post-surgery T3: 24 hours post-surgery T4: 48 hours post-surgery

    Time frame: Postoperative 6 hours, 12 hours, 24 hours, and 48 hours

  2. Effective Presses of the Pain Pump

    The number of effective presses of the pain pump will be recorded for each patient during their hospital stay to evaluate the effectiveness of the pain pump in alleviating postoperative pain.

    Time frame: 48 hours post-surgery

  3. Need for Rescue Analgesia

    This outcome will document whether patients require additional rescue analgesia postoperatively to assess the adequacy of the initial analgesic regimen.

    Time frame: 48 hours post-surgery

  4. Number of participants experience feelings of drowsiness

    Patients may feel unusually tired or sleepy after surgery. This can affect their attention and reaction times, increasing the risk of falls or other accidents.

    Time frame: day 2 post-surgery

  5. Time to Ambulate

    This outcome will measure the time taken for patients to ambulate (get out of bed)

    Time frame: Perioperative

  6. Time to Flatus

    This outcome will measure the time taken to pass gas post-surgery.

    Time frame: Perioperative

  7. Number of participants experience feelings of Dizziness

    Patients might experience feelings of dizziness or loss of balance. This reaction can lead to discomfort and potential dangers when the patient is standing or walking.

    Time frame: day 2 post-surgery

  8. Number of participants experience feelings of Nausea

    Patients may experience a sensation of wanting to vomit or feelings of nausea. This can impact their appetite and contribute to further discomfort.

    Time frame: day 2 post-surgery

  9. Number of participants experience feelings of Vomiting

    In some cases, nausea may develop into vomiting, leading patients to actually expel contents from their stomach. This can affect recovery and may lead to dehydration or electrolyte imbalances.

    Time frame: day 2 post-surgery

Individual participant data

Plan to share: No — For our study "Effects of Different Doses of Nalbuphine on Anxiety and Depression in Patients Undergoing Ectopic Pregnancy Surgery: A Prospective, Randomized, Controlled Study" we have decided not to share Individual Participant Data (IPD). This decision is due to privacy concerns, data security requirements, ethical approval limitations, legal restrictions, and the study's design which did not accommodate data sharing. We believe this aligns with ethical standards and operational capabilities.
