RESUMO
BACKGROUND AND IMPORTANCE: The use of drains, including suction drains in neurosurgery is individual preference-based, rather than scientific evidence-based. Furthermore, the use of suction drains has been associated with significant risks to patients, including sudden death. CLINICAL PRESENTATION: We present 2 cases of unfortunate sudden deaths following uneventful cranioplasty procedures, both of which were associated with the use of a suction drain. We also review the literature focusing on the benefits and risks in the use of suction drains, and discuss pathophysiological mechanisms underlying sudden death associated with their use. CONCLUSION: There is no substantial evidence to support the use of suction drains in neurosurgery. Furthermore, they have been associated with significant complications, including risk to life. Our experience and literature review suggest that the risk of sudden death is disproportionately higher following cranioplasty. We do not recommend the use of suction drains in cranial neurosurgery, and we strongly recommend against their use in cranioplasty procedures.
