Summary

Management of traumatic rib fractures continues to be a challenge for trauma surgeons. Currently, many analgesic options are available to patients suffering from rib fractures. Formulations currently used for conventional intercostal nerve blocks (CINB) are relatively safe, do not require additional equipment or specialized anesthesia personnel, do not require catheter repositioning, and provide improved analgesia immediately over the aforementioned systemic therapies. A goal of these authors to introduce an additional safe option for extended local analgesia in the setting of multiple rib fractures given the inconclusive evidence supporting or refuting the current standard of care

Detailed description

The objective of this study is to quantify and draw inferences on the efficacy of a multiple level liposomal bupivacaine intercostal nerve blockade (LBINB) in patients with multiple traumatic rib fractures. The primary objective is to assess the quality and duration of analgesia based on numeric grading pain scale, improvement in pulmonary function parameters, reduction pulmonary complications, and duration of hospitalization in patients receiving LBINBs relative to those receiving the current standard of care, CEA, in patients recovering from multiple traumatic rib fractures. The secondary objective of this study is to assess cost and rate of complications associated with LBINB relative to CEA. This is a two arm, randomized trial. Patients suffering multiple traumatic rib fractures will be offered CEA or LBINB. As the current standard of care, CEA will serve as the control, and outcomes measured in patients receiving LBINB will be statistically evaluated relative to the CEA control group. All patients will receive standardized NSAID and opioid analgesia protocol for break through pain, as well as standardized routines for pulmonary hygiene and physiotherapy. Indications for CEA and LBINB in this study include patients suffering from traumatic thoracic injury with greater than or equal to 3 fractured ribs

Interventions

Type	Name	Description
DRUG	Bupivacaine Liposome Injection	Under ultrasound guidance, corresponding ribs will be identified. 3-5 ml of a 1.3% (13.3 mg/mL) of liposomal bupivacaine will be drawn into a syringe with a 1.5-in, 22-gauge needle. The needle will then be advanced 20° cephalad to the skin 3-4 cm lateral to midline at the level of each fractured rib, and 1-2 ribs levels above and below injury. The needle will be advanced 3 mm below the inferior margin of the rib, placing the tip in the space containing the neurovascular bundle. Following negative aspiration for blood or air, 3-5 mL of local anesthetic will be infused and the needle withdrawn. No more than 266 mg, or 20 ml, of the 1.3% (13.3 mg/mL) liposomal bupivacaine solution will be injected
DRUG	Bupivacaine	The anesthesia department will manage CEA. If possible, the patient will be in the sitting position. The skin will be prepped with chlorhexidine and sterilely draped. 3 mL of lidocaine 1% will be infiltrated the closest interspace to the rib fractures between T4 -T12. A Touhy needle will be inserted, the epidural space identified by loss of resistance technique. An epidural catheter will then be inserted to a depth of 12cm. 3 mL of test solution with lidocaine 1.5% with epinephrine, 1:200,000 will be injected with continuous EKG and SpO2 monitoring. Delivery of a 0.125% bupivacaine solution be continuously infused and titrated based on the patient's clinical status
