Pharyngeal Packing

Abstract Background: Pharyngeal packing (PP) is commonly performed to reduce the incidence of perioperative blood ingestion (PBI) in nasal surgery (NS), and thus the incidence and severity of postoperative nausea and vomiting (PONV). This study examined the effects of PP on the perioperative gastric volume (GV) and PONV in patients undergoing NS, by ultrasound assessment. Methods: Patients undergoing elective NS [septoplasty, septo-rhinoplasty (SRP) and functional endoscopic sinus surgery (FESS)] were randomised to receive or not receive PP. In the PP group, pharyngeal packs were placed after the orotracheal intubation. Ultrasound assessments were performed for all patients preoperatively (before the anaesthesia induction) and postoperatively (before the extubation). The antero-posterior (AP) and cranio-caudal (CC) antral diameters, antral cross-sectional area (ACSA), and total GV were calculated. PONV incidence and severity were rated. These variables were compared between timepoints and groups, and in the subgroup analyses according to the surgery type. Pearson correlation analysis was performed to assess correlations between the variables. Results: AP and CC diameters and ACSAs were greater postoperatively than preoperatively in the PP and non-PP groups (n = 44 each; all p < 0.05). Postoperative AP and CC diameters and the ACSA were greater in the non-PP than in the PP group (all p < 0.05). Postoperative AP diameters were greater than preoperatively in patients undergoing SRP and FESS, and the postoperative CC diameter and ACSA were greater than preoperatively in patients undergoing SRP (all p < 0.05). Surgery duration was correlated positively with postoperative AP diameter (r = 0.380, p < 0.05), CC diameter (r = 0.291, p < 0.05), and ACSA (r = 0.369, p < 0.05). Patients who underwent septoplasty surgery, PP was decreased PONV incidence and severity at the first four hours, postoperatively (p < 0.05). Conclusions: The study findings indicate that PP reduces the increase in the perioperative GV due to PBI in an elective NS. It is therefore a useful and safe means of reducing the risk of perioperative pulmonary aspiration in such surgeries.

Sellick’s maneuver is a technique in which pressure is applied over the cricoid cartilage to occlude the upper part of esophagus which passes behind it. It is used to prevent regurgitation of gastric and esophageal contents and gastric distension during intubation and mask ventilation. This research is conducted to determine the efficacy of Sellick's maneuver in preventing gastric distension during mask ventilation using ultrasound. Sixty patients posted for elective surgery were selected and randomly allocated to a group receiving Sellick's Maneuver (SM) or No Sellick's Maneuver (NSM). Patients of both groups had their gastric antral cross sectional area (CSA) measured using ultrasound before induction of anesthesia and after intubation and mask ventilation. The SM group was intubated after application of Sellick's maneuver. Gastric volume was then calculated from the gastric antral CSA. Changes in gastric volume among SM and NSM group were assessed to determine whether Sellick's maneuver is effective in preventing gastric distension. Changes in gastric antral CSA and gastric volume before anesthesia induction and post-intubation is lower in the SM group as compared to the NSM group. Sellick's Maneuver is effective in preventing gastric distension.

Background In addition to its hemostatic and stabilization role, biodegradable nasal packing can be used as a carrier for drugs after functional endoscopic sinus surgery (FESS). The aim of this study was to compare the influence of biodegradable synthetic polyurethane foam (NasoPore) soaked with ciprofloxacin, or betamethasone, or both to the same foam soaked with saline after FESS. Methods 120 adults with chronic rhinosinusitis, with and without polyps, directed for bilateral full-house FESS were enrolled for the study. The patients were randomized and blinded into 3 groups, depending on the type of postoperative procedure applied. Thus, NasoPore soaked with antibiotic was provided to the first group; in the second group, the steroid was used; and the combination of both, in the third group. In each case, the aforementioned procedure was administered on one side of the nose, while NasoPore was soaked in saline on the other, at the end of the surgery, respectively. The patients were requested to complete a questionnaire during their postoperative visits at 2, 10, 30, 90, and 180 days, scoring the level of complaints on the VAS scale, separately for each side. The evaluation of the healing process was performed at each visit using rigid endoscopy and subsequently rated on numerical scales. Results Decreased mucosal edema and secretion; reduced Lund-Kennedy score; and favorable influences on facial pressure, nasal blockage, and smell were most evidently seen in the group receiving the antibioticsteroid combination. Conclusions The application of biodegradable nasal packing with betamethasone and ciprofloxacin in sino-nasal surgery has positive effects not only on the healing process but also impacts patient’s comfort. To optimize it, however, further research is needed.

ABSTRACT Objective: The aim of the present study was to locate mast cells in chronic periapical lesions (granulomas and cysts) by using histochemical techniques and toluidine blue staining. Methods: A quantitative, descriptive, cross-sectional and retrospective research was performed. The sample was obtained from histopathological reports in the archives of the laboratory of surgical pathology of the University of Pernambuco between November 2014 and May 2015. Results: Sixteen cases of granuloma and 21 cases of periapical cysts were selected. The stained slides were analyzed by two examiners at different times, in a double-blind study. Mast cells were found in 13 (61.9%) of the periapical cyst cases, located in the capsule of the lesion. In the periapical granuloma cases, mast cells were found in eight cases (50%), located in the granulation tissue. Conclusion: Mast cells were detected in both cysts and periapical granuloma, located in the capsule and granulation tissue, respectively. Mast cells were more prevalent in periapical cysts than in periapical granuloma.
