Commentary

In the current medical climate aimed at reducingunnecessary hospitalization, hospital costs, and resource utilization, ambulatory care centers and outpatient surgical popularity are on the rise[1]. Technological advancements have allowed a shift in the surgical paradigm towards minimally invasive surgery with evidence demonstrating smaller incisions, reduced soft tissue injury, operative time, estimated blood loss, and postoperative pain, lower rates of complications, and improved postoperative patient function compared to their open counterparts[2-4]. Successful efforts to minimize soft tissue injury have resulted in faster recovery times, time to rehabilitation, and shorter length of hospital stay[5].In effort to meet the growing demand of ambulatory surgery, anesthetic techniques have evolved to reduce perioperative morbidity and adverse medication side effects associated with general anesthesia as well as reduce postoperative pain in order to prevent overconsumption of narcotic medications.

Postoperative nausea and vomiting (PONV) is a major concern associated with general anesthesia affecting 20-35% of general surgery, and up to 80% of high-risk patients and may result in hospital admission following outpatient surgery[1,6,7]. Risk factors associated with PONV include female gender, age greater than 50-years-old, nonsmoking status, and a history of PONV or motion sickness[1,6]. In regards to anesthesia, an increased risk of PONV has been reported with use of volatile anesthetics, nitric oxide, and intra- or postoperative opioid medications. Similarly, it has been demonstrated that an increase in 30 minutes of operative time was associated with a 60% increase in PONV risk. In order to minimize risk, studies have demonstrated using regional anesthesia rather than general anesthesia and propofol for anesthesia induction are associated with a reduced baseline risk of PONV[6]. Similarly, avoiding volatile anesthetics or nitric oxide, and minimizing intra- and postoperative opiates are also associated with a reduced baseline risk. Postoperatively, administration of first-line antiemetics such as 5-hydroxytryptamine receptor antagonists (i.e.ondansetron) and steroid medications (i.e.dexamethasone) are commonlyused in the prophylaxis and treatment of PONV. Additional concerns for outpatient surgical procedures result from postoperative pain control and the use of opiod medications. Common adverse effects associated with opiate use include nausea and vomiting, constipation, drowsiness, dizziness, and dry mouth. Reduction in postoperative morbidity associated with opiate consumption is largely the result of cyclooxygenase inhibitor and non-steroidal anti-inflammatory (NSAIDs) use[1].

In addition to decompression procedures such as laminectomy, facetectomy, foraminotomy, and discectomy, the senior surgeon commonly performs anterior cervical discectomy and fusion (ACDF) in an ambulatory Surgicenter setting. In order to minimize complications and efficiently perform these procedures, the senior surgeon has employed a multidimensional approach to patient care, assembling a multidisciplinary team to adequately meet patient’s needs. Based on experience and careful observation of outcomes, the senior surgeon and his team of anesthesiologists commonly usethe following medications for his outpatient procedures:initially, midazolam and fentanyl are administered in the preoperative holding area for sedation and analgesia, respectively. Once the patient is brought to the operating room and situated on the operating table, a mixture of lidocaine and propofol are administered. Lidocaine isgivento reduce the pain associated with a propofol injection, while propofol is given for sedation. Once the patient is asleep, a non-depolarizing neuromuscular blocker, such as vecuronium or rocuronium,is administered to paralyze the patient in order to perform endotracheal intubation. Maintenance anesthesia is accomplished with sevoflurane. A mixture of neostigmine and glycopyrrolate is administered postoperatively. Neostigmine is an acetylcholinesterase inhibitor working as the neuromuscular blocking reversal agent while glycopyrrolate is utilized to prevent the muscarinic side effects, such as bradycardia, associated with neostigmine use.Depending on patient comorbidities and history with anesthesia, the senior surgeon has also utilized succinylcholine for neuromuscular blockade and ketamine for maintenance.

Despite the popularity and effectiveness of outpatient and ambulatory spine surgery, it is important to recognize potential adverse effects associated with all aspects of the surgical experience. Proper patient selection and preparation for common surgical and anesthetic complications will result in reduced hospital admissions and postoperative patient morbidity. Through repetition and careful planning, the surgical team providing care in the outpatient setting has adjusted protocols and procedural timing to safely and efficiently meet their patient population’s needs. While the combination of medications listed above and the senior surgeon’s procedural experience has functioned forhis patient population, an individualized treatment plan incorporating patient comorbidities, medical, surgical, and anesthesia histories will result in improvements in patient outcomes.
