Brief Summary

I. Background: Patients with multiple rib fractures are challenging from both pulmonary and analgesia perspectives. Adequate pain management is essential in prevention of complications secondary to decreased inspiratory volume. Significant morbidity and mortality of rib fractures is secondary to severe pain that limits ribcage movement, decreases inspiratory volumes and causes inadequate cough. Decreased vital capacity predisposes patients to atelectasis, abnormal mucous clearance and pneumonia. The objective of this study is to assess the efficacy of the serratus anterior plane block (SAPB) in improvement of vital capacity in patients with multiple unilateral rib fractures when compared to conventional management with medications. Currently, evidence of efficacy of SAPB in managing pain secondary to multiple rib fractures is limited to case reports and series, none of which evaluate vital capacity. II. Significance: The findings of this study may indicate that SAPB is superior to pharmacological management in increasing vital capacity in patients with multiple unilateral rib fractures and suggest SAPB for first line therapy in patients with rib fractures. The findings may decrease the risk of pulmonary complications as well as the use of opiates in management of multiple rib fractures in the Emergency Department especially in patients with numerous comorbidities and contraindications to conventional treatment modalities. This study may support the need for training emergency medicine physicians in bedside SAPB in order to provide the optimal therapy for patient with multiple unilateral rib fractures. III. Study Objectives: The primary objectives are to evaluate whether ultrasound guided SAPB results in a greater improvement in percent predicted vital capacity compared to standard therapy with a sham injection. The investigators will also evaluate pain scores and the safety profile of the SAPB procedure compared to those receiving standard analgesia. IV. Hypothesis: The primary hypothesis is that SAPB is superior to sham injection in improving the percent of predicted vital capacity. The secondary hypothesis is that SAPB will have greater improvement in pain scores and have a superior safety profile compared to placebo injection.

Outcome Measures

Primary Outcomes (1)

  • Pain Control

    Pain score on 11 point Numeric Rating Scale ranging 0-10 with 0 being no pain, 5 being moderate pain, and 10 being very severe pain

    60 minutes

Study Arms (2)

serratus anterior plane block group

ACTIVE COMPARATOR

The injection of bupivicaine into the chest muscle is performed with an ultrasound machine which can see the needle as it enters the muscle. The skin is cleaned with a sterile solution and the needle is guided right next to the chest muscle where either the bupivicaine injected. After the injection, the needle is taken out.

Drug: AcetaminophenDrug: Bupivacain

Placebo injection group

PLACEBO COMPARATOR

The injection of normal saline into the chest muscle is performed with an ultrasound machine which can see the needle as it enters the muscle. The skin is cleaned with a sterile solution and the needle is guided right next to the chest muscle where saline is injected. After the injection, the needle is taken out.

Drug: AcetaminophenDrug: Saline

Interventions

receive ketamine 0.15 mg/kg IV in 100 mL normal saline over 30 minutes for pain

Placebo injection groupserratus anterior plane block group

The injection of bupivicaine into the chest muscle is performed with an ultrasound machine which can see the needle as it enters the muscle.
