Summary

Rib fractures pose a significant healthcare burden with its associated morbidity, long term disability, and mortality. Pulmonary morbidity is increased in these patients as a result of diminished gas exchange from fracture induced pulmonary injury and from inadequate analgesia compromising both ventilation and pulmonary mechanics. Adequate analgesia is paramount in enhancing pulmonary hygiene aimed at preventing atelectasis and pneumonia. Numbing the nerves to the fractured ribs by injecting local anaesthetic (LA) improves breathing and reduces the risk of complications. Two techniques of regional anesthesia (erector spinae plane block (ESPB) and paravertebral block (PVB)) will be compared regarding their efficacy for treating pain caused by rib fractures. The LA is injected near nerves at two different locations. The PVB is immediately adjacent to the vertebrae, whereas the ESPB is slightly further away from the midline. Both techniques use ultrasound to ensure the LA is directed to the intended place. Adult patients with \> 3 consecutive fractured ribs will be consented, then randomised to receive either a ESPB or a PVB. It is expected that both groups will significantly improve in terms of pain score, opioids need, and breathing ability, however it is unclear which technique will provide better results and less complications.

Conditions

  • Rib Fracture Multiple

Interventions

PROCEDURE

Erector Spinae Plane Block

ESPB will be performed in sitting or lateral decubitus position. The target vertebral level will be correspond to the approximate mid-point of the extent of fractured ribs. The tip of the transverse process of the target vertebra will be identified using the high-frequency linear placed in cephalocaudal orientation about 3 cm to the spinous process. The skin and subcutaneous tissue will be infiltrated with 2-3 ml of 2% lignocaine. With the transducer fixed over the targeted TP, a 22-gauge 88-mm needle (Spinocan, B. Braun, Germany) will be advanced in-plane to the ultrasound beam in a cephalo-caudal direction to contact the TP. Correct needle tip position will be confirmed by doing alternating aspiration to confirm lack of inadvertent vascular puncture with injection of 1-2 ml of saline and visualizing linear fluid spread deep to erector spinae muscle, separating it from the TP. A bolus dose (2ml/segment) of plain bupivacaine 0.5% plus 4mg of Dexamethasone will be injected.

PROCEDURE

Paravertebral Block

TPVB will be performed at a spinal level midway between the uppermost and the lowest fractured rib with the patient in sitting or lateral decubitus position (with patients lying on their unaffected side). The ultrasound-guided technique will be used. A high-frequency linear transducer will be used to confirm the levels of the fractured ribs. The most cephalad and most caudad fractured ribs will be identified first. The fractured rib in the middle will be then identified, and the rib will be then traced back medially. After skin and subcutaneous tissue infiltration with 2-3 ml of 2% lignocaine, a 22-gauge 88-mm needle (Spinocan, B. Braun, Germany) will be inserted in a lateral-to-medial direction until the needle tip entered the paravertebral space. 1-2 ml of Saline will be injected into the paravertebral space while observing the pleura being moved deeply. A bolus dose (2ml/segment) of plain bupivacaine 0.5% plus 4mg of Dexamethasone will be injected.
