Background: Spinal opioid administration is an excellent option to separate the desirable analgesic effects of opioids from their expected dose-limiting side effects to improve postoperative analgesia. Therefore, physicians must better identify either specific opioids or adequate doses and routes of administration that result in a mainly spinal site of action rather than a cerebral analgesic one. Methods: The purpose of this topical review is to describe current available clinical evidence to determine what opioids reach high enough concentrations to produce spinally selective analgesia when given by epidural or intrathecal routes and also to make recommendations regarding their rational and safety use for the best management of postoperative pain. To this end, a search of Medline/Embase was conducted to identify all articles published up to December 2013 on this topic. Results: Recent advances in spinal opioid bioavailability, based on both animals and humans trials support the theory that spinal opioid bioavailability is inversely proportional to the drug lipid solubility, which is higher in hydrophilic opioids like morphine, diamorphine and hydromorphone than lipophilic ones like alfentanil, fentanyl and sufentanil. Conclusions: Results obtained from meta-analyses of RTCs is considered to be the 'highest' level and support their use. However, it's a fact that meta-analyses based on studies about treatment of postoperative pain should explore clinical surgery heterogeneity to improve patient's outcome. This observation forces physicians to use of a specific procedure surgical-based practical guideline. A vigilance protocol is also needed to achieve a good postoperative analgesia in terms of efficacy and security.

Purpose: The purpose of the study was to evaluate the effects of postoperative oral care using cold therapy on nausea, vomiting and oral discomfort after laparoscopic myomectomy. Method: The study was conducted with an experimental group (n=29) and a control group (n=35) sampled from patients admitted to a women's hospital in a metropolitan city in Korea. Data were collected between October 10, 2011 and January 31, 2012 and analyzed using Chi-square, Fisher's exact test, t-test, and repeated measure ANCOVA with SPSS/WIN 19.0. Results: After the intervention, postoperative nausea (p<.001) and oral discomfort for patients in the experimental group were significantly lower than in the control group. There were significant differences in the presence of vomiting between both groups at 12 hours (p<.001) and 24 hours (p=.003) after leaving the recovery room. Conclusion: Oral care using cold therapy was found to be an effective nursing intervention for reducing postoperative nausea, vomiting and oral discomfort up to 24 hours after recovery in patients with laparoscopic myomectomy.
The concept of PCA(Patient Controlled Analgesia) was first described in 1968, by Sechzer. The earliest descriptions of actual self-administered PCA machines were by Forrest et al. In gastric bypass surgery, cesarian section, orthopedic surgery etc, PCA is widely used in the control of postoperative pain. Previous Studies have shown that PCA provides effective pain-control for the postoperative patient. The postoperative pain-control is a problem that should be solved in surgery. Especially in orthognathic surgery, it is not same as in the case of maxillofacial trauma surgery or of tumor surgery: most orthognathic surgery patients are under operation not accustomed to pains, and difficulties in pain-complaint due to IMF(Intermaxillary fixation), postoperative nausea, and vomiting are additional problem. In this study, we have compared PCA and IM analgesics with respect not only to time request but also to the quality of postoperative pain control.

Background: Odontogenic cysts associated with lower third molar are common. The prognosis for surgical treatment is relatively good. However, postoperative infection discourages the clinicians. Hence, we would like to investigate the factors associated with infection after surgical treatment of cysts associated with the mandibular third molar. Methods: We retrospectively reviewed the medical and radiographic records of 81 patients who were diagnosed with dentigerous cyst or odontogenic keratocyst and underwent cyst enucleation. The factors affecting postoperative infection were divided into host factor, treatment factor, and cystic lesion factor. To identify the factors associated with postoperative infection, we attempted to find out the variables with significant differences between the groups with and without infection. Results: A total of 81 patients (64 male and 17 female) were enrolled in this study. There was no statistical relationship about the postoperative infection between all variables (gender, smoking, diabetes mellitus, age, bone grafting, related tooth extraction, previous marsupialization or decompression, type of antibiotics, cortical perforation associated with cystic lesion, preoperative infection, preoperative cyst size). Conclusions: The results of this study suggest that it is not necessary to avoid bone grafts that are concerned about postoperative infection.

Objectives: The aim of this study was to evaluate correlations between anxiety and preoperative pressure pain assessments and postoperative pain and analgesic requirements in impacted lower third molar tooth surgery. Materials and Methods: This prospective study enrolled 60 patients who underwent impacted lower third molar surgery. The preoperative State-Trait Anxiety Inventory-I (STAI-I), pressure pain threshold, and pressure pain tolerance scores were measured. At 2, 4, 6, 12, and 24 hours, and at 6 days following surgery, the patients scored their pain on the visual analogue scale and recorded their analgesic drug usage. The data were evaluated, and the results were statistically analyzed. Results: Of the 60 patients, 38 were female. Mean age was 24.62±7.42 years. The study found no relationship between preoperative pressure pain assessments and postoperative pain (P>0.05). There was also no relationship observed between preoperative STAI-I scores and postoperative pain (P>0.05). However, there was a positive correlation between operation time and total medication taken (P<0.05). Conclusion: Preoperative pressure pain threshold, pressure pain tolerance, and anxiety level had no significant effects on postoperative pain and analgesic requirements in impacted lower third molar surgery.
Background: The aim of this randomized, triple-blind trial was to determine the anesthetic, analgesic, and hemodynamic effects of articaine and bupivacaine in the extraction of impacted mandibular third molar teeth. Methods: Twenty-six patients who underwent removal of bilaterally symmetric mandibular third molars were randomly assigned to articaine and bupivacaine groups in a split-mouth design. The onset of anesthetic action, intraoperative comfort, total amount of solution used, duration of postoperative anesthesia and analgesia, rescue analgesic use, postoperative pain, intraoperative bleeding, and hemodynamic parameters were evaluated. Results: In the articaine group, the onset of anesthetic activity was faster, intraoperative comfort was greater, and effective anesthesia required less local anesthetic solution. The bupivacaine group showed a significantly longer duration of postoperative anesthesia and analgesia, in addition to lower visual analog scale values at 6 and 48 hours postoperatively. There were no significant differences between the two solutions regarding rescue analgesic medication use, intraoperative bleeding, or hemodynamics. Conclusion: Articaine showed greater clinical efficacy than bupivacaine in intraoperative anesthesia, achieving faster onset of anesthetic action and greater patient comfort while also requiring less reinforcement during surgery. However, bupivacaine was superior in terms of postoperative anesthesia, reducing postoperative pain due to its residual anesthetic and analgesic effects. Both anesthetic solutions led to similar hemodynamics at low doses in mandibular third molar surgery

This systematic review and network meta-analysis aimed to answer the following focused research question: "Does the type of endodontic sealer affect the postoperative pain in patients who received endodontic treatment?" Different databases and grey literature were surveyed. Only one randomized controlled trial were included. The risk of bias in the studies was evaluated by using the Cochrane Collaboration's tool. A random-effects meta-analysis was conducted to compare the risk and intensity of postoperative pain. The quality of the body of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. Out of 11,601 studies, 15 remained for qualitative analyses and 12 for meta-analysis. Seven studies were classified at high risk of bias, and 8 studies raised some concerns. No significant differences between the endodontic materials were observed in the direct comparisons, both in risk and in intensity of postoperative pain (pairwise comparisons with 2 studies: I2 = 0%; p > 0.05 and 8 studies: I2 = 23%; p > 0.05, respectively). The certainty of the evidence was graded as low or moderate. There was no difference in the risk and intensity of postoperative pain after filling with different endodontic sealers. Further systematic reviews should be conducted.
Purpose: Hip microinstability is defined as hip pain with a snapping and/or blocking sensation accompanied by fine anatomical anomalies. Arthroscopic capsular plication has been proposed as a treatment modality for patients without major anatomic anomalies and after failure of properly administered conservative treatment. The purpose of this study was to determine the efficacy of this procedure and to evaluate potential predictors of poor outcome. Materials and Methods: A review of 26 capsular plications in 25 patients was conducted. The mean postoperative follow-up period for the remaining patients was 29 months. Analysis of data included demographic, radiological, and interventional data. Calculation of pre- and postoperative WOMAC (Western Ontario and McMaster Universities Osteoarthritis) index was performed. Pre- and postoperative sports activities and satisfaction were also documented. A P<0.05 was considered significant. Results: No major complications were identified in this series. The mean pre- and postoperative WOMAC scores were 62.6 and 24.2, respectively. The WOMAC index showed statistically significant postoperative improvement (P=0.0009). The mean satisfaction rate was 7.7/10. Four patients with persistent pain underwent a periacetabular osteotomy. A lateral center edge angle ≤21° was detected in all hips at presentation. We were not able to demonstrate any difference in postoperative evolution with regard to the presence of hip dysplasia (P>0.05), probably because the sample size was too small. Conclusion: Capsular plication can result in significant clinical and functional improvement in carefully selected cases of hip microinstability.
Background: Postoperative atrial fibrillation (AF) is a common complication after coronary artery bypass graft (CABG) surgery. Although postoperative AF is regarded as benign, transient and self-limited, it has been associated with increased morbidity, thromboembolic events and an increased duration and cost of hospitalization. Material and Method: From January 1994 to December 2007, 190 patients that had isolated CABG surgery were divided into two groups. Group 1 (n=139) involved those who had postoperative atrial fibrillation, and group 2 (n=51) did not have any such events. We reviewed the medical records retrospectively including the incidence of postoperative AF, patient characteristics, surgery related factors and the outcome of the patients with postoperative AF. Result: The frequency of postoperative AF was 26.8%, the conversion rate to regular sinus rhythm before discharge was 82.4%; 82.4% of the AF developed within the first three postoperative days. Although the postoperative AF group was significantly older and had a prolonged postoperative Intensive care unit (ICU) stay, there was no difference in the aortic crossclamp time or duration of hospitalization. No spontaneous defibrillation at declamping, and longer duration of cardiopulmonary bypass were significantly related to the development of postoperative AF. However, postoperative treatment with a beta blocker was associated with a decreased incidence of postoperative AF. The multivariate analysis showed that age and ICU stay were significantly associated with the development of POAF. Spontaneous defibrillation and postoperative beta blocker treatment were significantly associated with a decreased frequency of POAF. Conclusion: AF after CABG surgery is a common complication associated with increased morbidity and a longer ICU stay. Therefore, various strategies aimed at reducing AF, and its complications, such as postoperative treatment with a beta blocker should be considered.

Purpose: Acute liver failure after massive partial hepatectomy is critical condition with high mortality. To prevent postoperative liver failure from being induced by a massive partial hepatectomy, many doctors do a minimal resection on the single lobe of the liver that might cause postoperative bleeding from the remaining ruptured parenchyma. The objective of this study was to assess clinical experience with postoperative hepatic arterial embolization to control bleeding from the remaining ruptured liver during the postoperative period. Methods: This retrospective 4-year study was conducted from May 2002 to April 2006 and included consecutive patients who had sustained massive hepatic injuries and who had undergone a laparotomy, followed by postoperative hepatic arterial angiographic embolization to control bleeding. Data on the injury characteristics, the operative treatment and embolization, and the amount of transfused packed red cells (PRBC) were gathered and analyzed. In addition, data on the overall complications and survival rate were collected and analyzed. Results: Every case showed severe liver injury, higher liver injury scaling grade IV. Only ten cases involved a ruptured bilateral liver lobe. A lobectomy was done in 6 cases, a left lobectomy was done in 3 cases, and a primary suture closure of the liver was done in 2 cases. Suture closure was also done on the remaining ruptured liver parenchyma in cases of lobectomies. The postoperative hepatic arterial embolizations were done by using the super-selection technique. There were some cases of arterio-venous malformations and anomalous vessel branches. The average amount of transfused PRBC during 24 hours after embolization was $2.36{\pm}1.75$, which statistically significantly lower than that before embolization. Among the 11 cases, 9 patients survived, and 2 died. There was no specific complications induced by the embolization. Conclusion: In cases of postoperative bleeding in severe hepatic injury, if there is still a large amount of bleeding, postoperative hepatic arterial embolization might be a good therapeutic option.
