BACKGROUND: Tracheal intubation is closely associated with increases in intraocular pressure (IOP); however, the effects of double-lumen tube (DLT) intubation on IOP have not been validated. Systemic hypertension (HTN) is another factor that may increase IOP. In this study, we observed differences in IOP increases between DLT and single-lumen tube (SLT) intubation, and evaluated the influence of underlying HTN during rapid sequence induction.METHODS: Sixty-eight patients were allocated into one of the following group: SLT/without HTN (n = 17), SLT/HTN (n = 17), DLT/without HTN (n = 17), and DLT/HTN (n = 17). An SLT was inserted for orthopedic or gynecological surgery, and a DLT was inserted for lung surgery after rapid sequence induction using succinylcholine. IOP was measured before anesthetic induction and until 10 min after intubation using a handheld tonometer (Tono-Pen AVIA®).RESULTS: In the DLT/without HTN and DLT/HTN groups, the maximum increases in IOPs after tracheal intubation were 7.9 and 12.2 mmHg, respectively, compared to baseline. In the SLT/without HTN and SLT/HTN groups, the maximum increases were 5.0 and 4.9 mmHg, respectively, compared to baseline. In comparisons between patients with and without underlying HTN, the values of IOPs were comparable.CONCLUSIONS: Tracheal intubation with a DLT is associated with more increases in IOPs than with an SLT in rapid sequence induction. Well-controlled underlying hypertension did not increase IOP during tracheal intubation.

Enhanced recovery after surgery (ERAS) is a multimodal and multidisciplinary approach to maintaining physiologic function and improving recovery for surgical patients. The ERAS protocol is based on a range of empirical evidence, and consensus ERAS guidelines for various surgical procedures have been published. The elements of the ERAS protocol include minimal preoperative fasting and carbohydrate treatment instead of overnight fasting; no routine use of preoperative bowel preparation; minimally invasive surgical techniques; standard anesthetic protocol; optimal fluid management rather than generous intravenous fluid administration; prevention and treatment of postoperative nausea and vomiting; active prevention of perioperative hypothermia; multimodal approaches to controlling postoperative pain; and early oral intake and mobilization. Implementation of ERAS shortened hospital stays by 30% to 50% and reduced postoperative complications by 50%. A recent study reported that, when patient compliance with the colorectal ERAS protocol was over 70%, 5-year mortality fell by 42% compared with when compliance was below 70%. Auditing process compliance and patient outcomes are key measures for assisting clinicians implementing the ERAS program. As a perioperativist, an anesthesiologist can play a crucial role in implementing the ERAS program and contribute to protocol establishment, auditing, team education and team leadership. While the ERAS protocol was first implemented for colorectal surgery, as a result of its efficacy, it is now being used in nearly all major surgical specialties.
