Anesthesia Progress Volume 69: Issue 1

Objective:

Factors related to perioperative dental injury have likely changed as a variety of airway devices and preventive measures have been introduced. This retrospective chart review used data from an institutional registry to evaluate the incidence, timing, and contributing factors of patient self-reported dental injury and to assess the impact of dental injury on patient satisfaction.

Methods:

Multivariate logistic analysis was performed on the records of 14,820 patients using the incidence of dental injury as the dependent variable and covariates in the anesthesia registry and a postoperative questionnaire as independent variables to investigate factors significantly associated perioperative dental injury. In addition, satisfaction with the anesthesia service was compared between patients with and without injury using a matched-pair population.

Results:

A total of 101 dental injuries were identified. Of those, 25% were associated with intubation and extubation in the operating room, while most other injuries occurred postoperatively. Duration of anesthesia (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00–1.03) and emergency surgery (OR, 1.92; 95% CI, 1.11–3.30) were independently associated with perioperative dental injury. Dental injury did not significantly decrease a patient's satisfaction with the anesthesia service (P = .441).

Conclusion:

Most perioperative dental injuries are unrelated to anesthesia procedures. However, the duration of anesthesia and emergency surgery were significantly associated with perioperative dental injury, while decreased patient satisfaction was not.

Objective:

The purpose of this prospective randomized study was to assess using a periodontal ligament (PDL) injection as an aide to decrease palatal infiltration pain.

Methods:

A total of 133 subjects randomly received a PDL injection and alternative palatal infiltration or a mock PDL injection and conventional palatal infiltration at 2 separate appointments. PDL injection was given in the mid-palatal sulcus of the maxillary first molar. Mock PDL injection consisted of only needle insertion. All subjects then received a palatal infiltration administered into the blanched gingival tissue 3 mm (alternative palatal infiltration) or 7 mm (conventional palatal infiltration) from the gingival collar. Subjects recorded needle insertion and solution deposition pain using a Heft-Parker visual analog scale (VAS).

Results:

The combined PDL injection and alternative palatal infiltration had significantly decreased mean VAS ratings for needle insertion and solution deposition pain (P < .0001). Incidence of moderate/severe pain for needle insertion and solution deposition was reduced from 65% to 1% and from 65% to 2%, respectively.

Conclusion:

Providing PDL anesthesia into the mid-palatal sulcus of the maxillary first molar and then administering an alternative palatal infiltration into the blanched collar around the PDL molar site led to significant reductions in needle insertion and solution deposition pain compared with a mock PDL and conventional palatal infiltration.

Objective:

The incidence of postoperative nausea and vomiting (PONV) after general anesthesia with total intravenous anesthesia (TIVA) was reported to be significantly lower than with volatile inhalational agents (13.3% vs 25%). However, no investigation of PONV risk factors associated with TIVA has ever been reported. This cross-sectional retrospective study aimed to investigate whether known risk factors influenced PONV in intubated general anesthetics utilizing TIVA for dental or oral and maxillofacial surgery.

Methods:

Subjects were 761 patients who underwent dental or oral and maxillofacial surgery under TIVA with propofol, fentanyl, and remifentanil. Univariate and multivariable logistic regression analyses were performed using PONV (within 24 hours) as the dependent variable and previously reported risk factors as independent variables.

Results:

Age (odds ratio [OR]: 1.020 per year decrease; 95% confidence interval [CI]: 1.0002–1.0418; P = .047) and female sex (OR: 2.73; 95% CI: 1.60–4.84; P < .001) were positively associated with PONV. Sagittal split ramus osteotomy (SSRO) (OR: 2.28; 95% CI: 1.21–4.33; P = .011) and bimaxillary osteotomy (OR: 5.69; 95% CI: 2.09–15.99; P < .001) were more likely to be associated with PONV than operations that were neither bimaxillary osteotomy nor SSRO. Late PONV (2–24 hours) had an ∼2.7 times higher incidence than early PONV (0–2 hours).

Conclusion:

These findings suggest further PONV countermeasures, aside from TIVA with propofol and prophylactic antiemetics for orthognathic surgeries especially bimaxillary osteotomy, are needed.
