Opioid Dispenser for Microdiscectomy/Laminectomy

The opioid crisis continues to plague the United States. While great strides have been made nationwide to decrease overprescribing, improvements are still needed to appropriately educate patients on the safe and responsible use, storage and disposal of opioids. Pain after surgery is often treated with opioid medications. Opioid medications can have side effects. Some side effects are relatively minor (constipation, nausea, vomiting), while others are more severe (sedation, abnormal breathing, etc.) and can lead to serious illness or death. Opioid pain medications when used the wrong way may also be addictive. Due to theses side effects, sometimes patients feel uncomfortable about taking these medications, and doctors prescribe them very cautiously. However, when used properly and safely, opioid pain medications are excellent pain relievers. Addinex, a technology company, has developed a device to help patients take opioids more safely. In this study the investigators aim to enroll a total of 30 patients who undergo spine surgery. Half will be randomly assigned to receive a standard pill bottle with opioids at discharge and will download a mobile app so that they can record their daily pain scores and the number of opioids they take for two weeks after surgery. The other half will receive the new opioid dispenser filled with opioids and a mobile app that generates a passcode that opens that device only at designated times. For this group of patients, every time the patient wants to take an opioid, they need to go to the app, enter their pain score before the app generates a passcode. The investigators will be tracking all study patients' opioid use and pain scores for the two weeks after surgery, will count how many pills they have left over 14 days after their surgery during a live telehealth session, and ask patients how they liked using the device. Results from this study will help understand if the Addinex device could potentially be useful to patients in the future after surgeries as opposed to typical pill bottles.

Measurement of Intraocular Pressure in Patients Undergoing Laminectomy in the Prone Position

Laminectomy surgeries, typically performed for lumbar disc herniation and spinal disorders, are often lengthy surgical procedures requiring patients to be in the prone position. While this position provides better visibility of the surgical field, it can lead to physiological changes in intraocular pressure (IOP) in anesthetized patients. An increase in IOP, though rare, has the potential to cause severe ocular complications such as postoperative vision loss (POVL), which is one of the most feared complications after spinal surgery. One of the main mechanisms of IOP elevation in the prone position is the impediment of venous return in the head and neck region due to gravity, leading to an increase in episcleral venous pressure. Additionally, direct mechanical pressure on the face and globe can also increase IOP. Anesthesia management can also play a role in IOP dynamics by affecting intrathoracic pressure and venous return. This complex interaction necessitates careful monitoring of eye health in anesthetized patients in the prone position. Non-contact tonometers offer a non-invasive, rapid, and reliable method for IOP measurement. They are particularly advantageous for repeated measurements in anesthetized patients. This clinical study aims to evaluate changes in IOP using a non-contact tonometer in patients undergoing laminectomy in the prone position and to identify anesthesia- and patient-related factors influencing these changes. The data obtained will contribute to the development of anesthesia and positioning strategies aimed at reducing the risk of ocular complications.
