What is the purpose of this trial?

This trial tests two anesthesia methods for individuals undergoing laparoscopic hiatal hernia surgery. The Opioid Sparing Anesthesia Protocol (OSA) uses fewer opioids, while the Opioid Based Anesthesia Protocol (OBA) follows the traditional opioid-based approach. The researchers aim to determine if reducing opioid use can decrease the need for them post-hospitalization and improve recovery outcomes, such as less nausea or shorter hospital stays. Individuals planning elective laparoscopic hiatal hernia surgery without drug allergies may be suitable for this trial. As an unphased trial, it offers participants the chance to contribute to innovative research that could enhance recovery experiences for future patients.

Do I have to stop taking my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. Please consult with the trial coordinators for guidance.

What prior data suggests that these anesthesia protocols are safe for hiatal hernia surgery?

Research has shown that using fewer opioids in anesthesia, like the method being tested here, can reduce side effects such as nausea while providing similar pain relief to traditional opioid-based methods. This approach uses drugs like dexmedetomidine and ketamine, which previous studies have found to be well-tolerated.

In contrast, opioid-based anesthesia involves drugs like fentanyl. Although effective for pain relief, these can cause side effects such as nausea or dizziness. Each method carries its own risks and benefits, but both have been safely used in surgeries before.

This trial aims to determine if reducing opioid use can lessen side effects while still managing pain effectively. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores different anesthesia protocols for hiatal hernia surgery, which traditionally relies on opioid-based methods. The Opioid Sparing Anesthesia Protocol (OSA) is unique as it uses dexmedetomidine and ketamine to reduce or eliminate the need for opioids, which can have addictive properties and side effects. This approach not only aims to manage pain effectively but also to enhance recovery by minimizing opioid-related complications. In contrast, the Opioid Based Anesthesia Protocol (OBA) uses fentanyl, a common opioid, but maintains a placebo aspect with a saline infusion for blinding purposes. By comparing these two approaches, researchers hope to find out if the OSA can provide equal or better pain management with fewer side effects, which could be a game-changer in surgical care.

What evidence suggests that these anesthesia protocols are effective for hiatal hernia surgery?

This trial will compare two anesthesia protocols for hiatal hernia surgery: the Opioid Sparing Anesthesia Protocol (OSA) and the Opioid Based Anesthesia Protocol (OBA). Research has shown that using fewer opioids during surgery, by incorporating alternatives like dexmedetomidine and ketamine as in the OSA protocol, can effectively manage pain. This approach is applied in surgeries such as hiatal hernia repair. Studies indicate that it reduces the need for opioids after surgery, leading to fewer side effects like nausea. Patients often experience similar pain relief compared to traditional methods that use more opioids, such as the OBA protocol. Some studies suggest that using fewer opioids can also lower medication costs. Overall, this method can improve recovery and reduce risks. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Opioid Based Anesthesia Protocol (OBA)
• Opioid Sparing Anesthesia Protocol (OSA)

Trial Overview

The study compares two anesthesia methods during hiatal hernia surgery: an opioid sparing protocol (OSA) and a traditional opioid based one (OBA). The goal is to see if OSA reduces opioid use after surgery while maintaining pain control and satisfaction.

How Is the Trial Designed?

Group I: Opioid Sparing Anesthesia Protocol Experimental Treatment 1 Intervention

The OSA protocol will include boluses of dexmedetomidine and ketamine at anesthesia induction, followed by a ketamine infusion that will continue until PACU discharge. Another bolus of ketamine will be administered upon surgical incision and another dexmedetomidine bolus will be given at surgical closure to reduce the use of opioids.

Group II: Opioid Based Anesthesia Protocol Experimental Treatment 1 Intervention

The OBA group will be administered a saline infusion at the same rate of the ketamine infusion (only while in the PACU) up until PACU discharge so that surgeons, patients, and PACU nurses will be blinded. The OBA group will be administered fentanyl 100 mcg IV for anesthesia induction followed by 50 mcg IV boluses when heart rate or systolic blood pressure is 20% above baseline throughout the case.

The Opioid Free Anaesthesia (OFA) protocol used in 38 patients undergoing laparoscopic bariatric surgery demonstrated effective pain control, with 68% of patients reporting no pain upon entering the Post Anaesthesia Care Unit.

The OFA protocol was found to be safe, with a high rate of successful hypertensive response control (88.1%) and low reliance on opioids, as only seven patients required a small dose of Pethidine post-surgery.

In a study of 257 obese patients undergoing laparoscopic bariatric surgery, those who received opioid-free anesthesia (OFA) had a significantly higher rate of not requiring morphine in the first 24 hours post-surgery (87%) compared to those who received opioid balanced anesthesia (OBA) (52%).

Among the OFA patients, those who received dexmedetomidine (OFAD) were more successful in avoiding morphine (93%) compared to those who received clonidine (OFAC) (81%), indicating that dexmedetomidine may be a more effective option for reducing postoperative morphine consumption.

In a study of 30 obese patients undergoing laparoscopic sleeve gastrectomy, nearly half (46.7%) did not need any opioids for pain relief after surgery, indicating the effectiveness of the new anaesthesia protocol.

The use of multimodal analgesia, including local anaesthetic infiltration, significantly reduced the overall opioid requirement, with an average of only 32 mg of pethidine needed per patient, suggesting a safer approach to pain management in bariatric surgery.

In a study of 172 patients undergoing major cervicofacial oncologic surgery, the opioid-reduced anesthesia (ORA) group required significantly less morphine (6.2 mg) compared to the standard opioid-based anesthesia group (10.1 mg), indicating a potential for reduced opioid consumption during surgery.

While ORA did not lead to lower postoperative pain scores or opioid requirements, it was associated with a reduced incidence of hypoxemia and the need for additional pressure-assisted ventilation, suggesting potential safety benefits that warrant further investigation in prospective studies.

In a study of 99 patients undergoing bariatric surgery, those who received opioid-free anesthesia (OFA) reported significantly less postoperative pain at both 24 and 48 hours compared to those who received opioid-based anesthesia (OBA).

Patients in the OFA group also experienced better overall recovery, as indicated by higher scores on the quality of recovery-40 questionnaire and lower postoperative opioid requirements.

In a study of 311 patients undergoing major surgeries, a total intravenous opioid-free anesthesia (OFA) protocol was successfully implemented, resulting in minimal use of IV morphine (only 2 mg on average) during recovery, indicating effective pain management without opioids.

The findings suggest that OFA is a safe and feasible approach, as it effectively managed the physiological stress responses during surgery and required very low opioid consumption in the postoperative period, supporting a shift away from traditional opioid-based anesthesia.
