Lumbosacral Epidural Access Technique

Check if the same lab product or an alternative is used in the 5 most similar protocols

In a midline approach at the lumbosacral intervertebral space (L7–S1), the needle was advanced perpendicularly into the skin until an increase in resistance was felt, indicating that the
ligamentum flavum had been reached. The stylet was removed, and an air-filled loss of resistance (LOR) syringe (Perifix; B. Braun) was connected to the needle. While the needle was advanced,
the operator pressed the syringe plunger until a LOR to air injection and a sudden LOR to needle advancement were felt.

Epidural Catheter Insertion for Anesthesia

Check if the same lab product or an alternative is used in the 5 most similar protocols

Before induction of anesthesia for patients allocated to TEA group, attending senior anesthetists who were not involved in the study inserted a 20 gauge epidural catheter (Perifix, B.Braun, Melsungen AG, Germany). The techniques were performed under aseptic precaution in the lateral position at T8 - T9 level. A midline approach with loss of resistance technique with saline was employed using an 18 gauge and an 80 mm Tuohy needle (Perifix, B.Braun, Melsungen AG, Germany). There were no drugs administered but test dose of 3 mL of Lidocaine 1% mixed with epinephrine 1: 200 000.

Continuous Tissue Pressure Measurement System

The CTP measurement system included a 20 gauge (0.45 mm internal diameter) closed end, reinforced nylon, disposable multipore epidural catheter (Perifix™, B. Braun Melsungen AG, Melsungen, Germany). The 1-m long saline-filled catheter was connected via a three-way stopcock to a disposable fluid pressure transducer (Deltran™ DPT-100, Utah Medical Products, Midvale, Utah) with a measurement range from −30 to 300 mmHg, sensitivity of 5 µV/V/mmHg, and accuracy of ±1%. A normal saline IV bag hung approximately one meter above the wrist allowed for introduction of saline drops to keep the catheter tip clear. Similar methodologies have been previously reported.8 (link),21 (link) System calibration was verified in bench testing by water column to 220 mmHg, prior to and following data collection.

Anesthetic Induction and Epidural Analgesia

Check if the same lab product or an alternative is used in the 5 most similar protocols

Induction of anesthesia was performed intravenously with sufentanil (0.3–0.6 μg/kg), propofol (1.5–2 mg/kg) and rocuronium (0.9–1 mg/kg). Additional boluses of sufentanil (0,1–0,2 μg/kg) were administered as needed. All patients were intubated with a double-lumen endotracheal tube for single-lung ventilation. Patients obtaining TEA received an epidural catheter (27 G catheter Perifix®, B.Braun, Melsungen, Germany) using an 18 G Tuohy needle. The epidural catheter was placed at thoracic level 7/8 or 8/9 interspace. The epidural space was identified by using the midline approach and the loss of resistance technique with normal saline. Epidural block analgesia was induced with 10 ml of bupivacaine 0,125% followed by 5–10 ml bupivacaine 0,125% every hour during surgery. PCA allocated patients received 3–5 mg piritramide as an iv bolus injection before the end of surgery and 1 g metamizole was administered to every patient in both groups as a short-term iv infusion before the end of surgery.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
