Orthognathic Surgery Patients (Maxillary Impaction and Setback plus Mandibular Advancement plus Genioplasty) Need More Intensive Care Unit (ICU) Admission after Surgery.

J Dent (Shiraz) 2015 Mar;16(1 Suppl):43-9

Statement Of The Problem: Due to shortage of ICU beds in hospitals, knowing what kind of orthognathic surgery patients more need ICU care after surgery would be important for surgeons and hospitals to prevent unnecessary ICU bed reservation.

Purpose: The aim of the present study was to determine what kinds of orthognathic surgery patients would benefit more from ICU care after surgery.

Materials And Method: 210 patients who were admitted to Chamran Hospital, Shiraz, for bimaxillary orthognathic surgery (2008-2013) were reviewed based on whether they had been admitted to ICU or maxillofacial surgery ward. Operation time, sex, intraoperative Estimated Blood Loss (EBL), postoperative complications, ICU admission, and unwanted complications resulting from staying in ICU were assessed.

Results: Of 210 patients undergoing bimaxillary orthognathic surgery, 59 patients (28.1%) were postoperatively admitted to the ICU and 151 in the maxillofacial ward (71.9%). There was not statistically significant difference in age and sex between the two groups (p> 0.05). The groups were significantly different in terms of operation time (p< 0.001). Blood loss For ICU admitted patients was 600.00±293.621mL and for those who were hospitalized in the ward was 350.00±298.397 mL. Statistically significant differences were found between the two groups (p< 0.001). Moreover, there was a direct linear correlation between operation time and intraoperative estimated blood loss and this relationship was statistically significant (r=0.42, p< 0.001). Patients with maxillary impaction and setback plus mandibular advancement plus genioplasty were among the most ICU admitted patients (44%), while these patients were only 20% of all patients who were admitted to the ward. As a final point, the result illustrated that patients who were admitted to the ICU experienced more complication such as bleeding, postoperative nausea, and pain (p< 0.001).

Conclusion: Orthognathic surgery patients (maxillary impaction and setback plus mandibular advancement plus genioplasty) due to more intraoperative bleeding and postoperative nausea and pain would benefit from ICU admission after surgery.

Remifentanil, ketamine, and propofol in awake nasotracheal fiberoptic intubation in temporomandibular joint ankylosis surgery.

J Craniofac Surg 2015 Jan;26(1):206-9

Background: Nasotracheal intubation of patients with temporomandibular joint (TMJ) ankylosis is a challenge for anesthesiologists. Awake fiberoptic intubation (AFOI) is the safest technique in patients with difficult airway. This study compares 3 different techniques of conscious sedation during AFOI in patients with TMJ ankylosis.

Methods: This study comprised 54 patients, American Society of Anesthesiologists physical status 1, scheduled for TMJ surgery. The patients were randomly allocated to remifentanil group (n = 18, 0.75 μg/kg over 30 seconds), ketamine group (n = 18, 0.25 mg/kg over 30 seconds), or propofol group (n = 18, 0.5 mg/kg over 30 seconds) for conscious sedation. The main determinants affecting the patient's outcome included intubation time, intubation conditions, and patient discomfort, which were determined by scoring system. In addition, postoperative patient dissatisfaction, hemodynamic stability, and respiratory impairment were measured.

Results: Intubation times were significantly different between groups (P < 0.001), where remifentanil had the shortest time (30.28 seconds). Intubation conditions (scores 0-3) were significantly different between groups (P < 0.001).In this context, remifentanil had score 3 (2-3), which was higher compared with 2 (1-3) for ketamine and 2 (1-2) for propofol. Patient discomfort score was lowest in the remifentanil group. Hemodynamic stability was maintained within groups, and its changes were not significant (P > 0.05). Postoperative patient's dissatisfaction was observed in 2, 3, and 5 patients in remifentanil, ketamine, and propofol groups, respectively. Respiratory impairment (apnea) recorded lowest in the remifentanil group.

Conclusions: Remifentanil was the best agent for AFOI, because it provided shorter intubation time, better intubation conditions, and least patient's complaint.Iranian registry no.: IRCT 201208061674N4 (
