Background: For sinus surgery, some centers favor total intravenous anesthesia (TIVA) over inhalation anesthesia. However, whether TIVA affects the patient's perceived quality of recovery remains unclear. This study used the Quality of Recovery-40 questionnaire (QoR-40) to compare patient recovery between surgical patients who received TIVA and those who received desflurane (DES) anesthesia. Methods:Eighty patients (20 to 65 years old) undergoing endoscopic sinus surgery were prospectively enrolled and randomized to either the TIVA (propofol and remifentanil infusion) or DES (desflurane inhalation and remifentanil infusion) group. The QoR-40 was administered before surgery, at 6 hours a er surgery, and on postoperative day 1 (POD1). Incidence of nausea and vomiting, remifentanil consumption, blood loss, and pain treatment were recorded. The influence of lesion extent (indexed as Lund-Mackay [LM] score) on recovery quality was also assessed.Results: Forty patients were randomized into the TIVA group, and 40 patients were randomized into the DES group. The QoR-40 score at 6 hours a er surgery was significantly higher in the TIVA group compared with the DES group (188.2 vs 182.6, respectively; p = 0.049), indicating a be er quality of recovery in the TIVA group. TIVA resulted in less blood loss (p < 0.0001). A high LM score (ࣙ12) was associated with lower QoR-40 scores at 6 hours a er surgery (180.2 vs 187.2, p = 0.028) and on POD1 (181.5 vs 190.3, p = 0.003). Conclusion:This study shows that the quality of recovery for endoscopic sinus surgery patients was be er with TIVA than with desflurane anesthesia. A high LM score was related to poorer recovery quality.

Background: Postoperative nausea and vomiting (PONV) are common side-effects following strabismus surgery. The present study aimed to compare the effects of different doses of dexmedetomidine (DEX) on PONV incidence in pediatric patients undergoing strabismus surgery. Methods: In this prospective randomized double-blinded study, 126 pediatric patients undergoing strabismus surgery were randomized into one of three groups: Placebo group, normal saline; DEX1 group, 0.3 μg/kg dexmedetomidine, and DEX2 group, 0.5 μg/kg dexmedetomidine. Oculocardiac reflex (OCR) events were recorded during surgery. PONV or postoperative vomiting (POV) was recorded for 24 h in the ward. Pediatric anesthesia emergence delirium (PAED) scale and emergence agitation (EA) scale were recorded in the recovery room. Results: Intraoperative OCR was significantly reduced in DEX2 group (42%) as compared to that of Placebo group (68%) (p = 0.0146). During the first 24 h post-op, the overall incidence of PONV was significantly lower in DEX2 group (10%) than that of Placebo group (32%) (p = 0.0142). There was no significant difference in POV among the three groups. PAED or EA scores among the three groups were similar during recovery time. Conclusion: Dexmedetomidine (0.5 μg/kg) reduced OCR and PONV without lengthening extubation time or recovery time in pediatric patients undergoing strabismus surgery.

BackgroundDexmedetomidine as an adjunct with opioids has been confirmed to spare opioids usage and improve analgesia for postoperative pain treatment. Furthermore, dexmedetomidine can attenuate the airway reflex. The aim of this study is to assess the safety and efficacy of dexmedetomidine combined with sufentanil for postoperative analgesia after partial laryngectomy.MethodsA total of 60 adult male patients were recruited and randomly allocated to receive sufentanil 1.0 μg ml−1 (Group S) or sufentanil 1.0 μg ml−1 plus dexmedetomidine 4 μg ml−1 (Group SD) for postoperative analgesia. The IV patient controlled analgesia (PCA) device was programmed to deliver 1.5 ml per demand with a 10 min lockout interval and 1.5 ml per hour background infusion. Cumulative consumption of sufentanil and pain intensity during 24 hour (h) after surgery were recorded. Coughing episodes per day, sleep quality, hemodynamic and respiratory profiles were measured.ResultsCompared with Group S, patients in Group SD required less sufentanil during the 0–24 h postoperative period (p < 0.0001) and reported significant lower pain intensity from the second postoperative hour to the end of the study (P < 0.0001). Daily coughing episodes, sleep disturbance was lower and patients’ satisfaction was higher in Group SD (P < 0.05). Decrease in heart rate and mean blood pressure from baseline at 1 h, 2 h, 3 h, 12 h, and 24 h after operation were significantly greater in Group SD (P = 0.00). The incidence of PCA related adverse events were comparable between the two groups.ConclusionDexmedetomidine/sufentanil combination for postoperatjve analgesia in partial laryngectomized patients resulted in significant sufentanil sparing, better analgesia, reduced frequency coughing episodes, and better sleep quality.Trial registrationChinese Clinical Registry (ChiCTR): ChiCTR-TRC-14004618, date of registration: 08 May 2014.

BackgroundKaposi’s sarcoma (KS)-associated herpesvirus (KSHV) is the etiologic agent of KS, the most common AIDS-related malignancy. The majority of KS tumor cells harbor latent KSHV virus but only a small percentage undergoes spontaneous lytic replication. Viral reactivation from latency is crucial for the pathogenesis and development of KS, but the cellular mechanisms underlying the switch between viral latency and replication are not well understood.MethodsThe level of let-7 miRNAs and MAP4K4 in KSHV infected 293T cells were quantified by real-time PCRs. Let-7 expression was silenced by the miRNA sponge technique. In let-7a transfected 293T cells, the expression of MAP4K4 was measured by real-time PCR and western blot. Luciferease expression was employed to examine the effect of let-7a on the 3’-untranslated region (UTR) of the MAP4K4 gene in 293T cells. Real-time PCR was used to quantify the KSHV copy numbers in BC-3 cells in which the expression of let-7a and/or MAP4K4 were altered. Finally, ERK, JNK and p38 protein production and their phosphorylation status were detected by western blots in let-7a or MAP4K4 transfected BCBL-1 cells.ResultsThe expression of microRNA let-7 was dramatically decreased in KSHV infected 293T cells, but that of MAP4K4 was increased significantly. Let-7a is physically associated with and targets the MAP4K4 3’UTR, and inhibits MAP4K4 expression at both mRNA and protein levels. MAP4K4 stimulates KSHV reactivation from latency, whereas let-7a inhibits the function of MAP4K4 by reversing the function of MAP4K4 on JNK, phospho-JNK and phospho-ERK1/2 levels.ConclusionOur results establish that let-7a specifically suppresses MAP4K4 expression, and further inhibits KSHV reactivation by interfering with the function of MAP4K4 on the MAPK pathway, highlighting let-7a as a potential treatment for KS.
