Abstract
BACKGROUND Catheter-related bladder discomfort (CRBD is a painful complication of intraoperative urinary catheterization after anaesthesia. We conducted this study to compare the effect of tramadol and lornoxicam for the prevention of postoperative CRBD. METHODS One-hundred twenty patients (aged 18-60 years, ASA physical status 1-2, undergoing elective uterine surgery requiring intraoperative urinary catheterization were randomly divided into three groups with 40 patients in each group. Group T received 1.5 mg/kg tramadol, group L received 8-mg lornoxicam, and group C received normal saline. The study drugs were administered intravenously at the end of the surgery. The incidence and severity of CRBD were reported at 0, 1, 2, and 6 h after arrival at the postanaesthesia care unit (PACU). RESULTS The incidence of CRBD was significantly lower in groups T and L than in group C at 1, 2, and 6 h after surgery. The incidence of moderate to severe CRBD was also significantly lower in groups T and L than in group C at 0, 1, and 2 h after surgery. The severity of CRBD reported as mild, moderate, and severe was reduced in groups T and L compared with group C at most times after surgery. Group T had a higher incidence of nausea than group C, and there were no differences in dizziness, drowsiness, or vomit among the three groups. CONCLUSIONS Tramadol and lornoxicam administered intravenously at the end of the surgery were both effective in preventing the incidence and severity of CRBD after uterine surgery. However, tramadol increased the incidence of nausea compared with saline, but there was no difference between tramadol and lornoxicam. TRIAL REGISTRATION ChiCTR2100052003. Registered on 12/10/2021.

Novel Screen-Printed Sensor with Chemically Deposited Boron-Doped Diamond Electrode: Preparation, Characterization, and Application. BIOSENSORS 2022; 12:bios12040241. [PMID: 35448301 PMCID: PMC9027657 DOI: 10.3390/bios12040241] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/08/2022] [Accepted: 04/11/2022] [Indexed: 05/27/2023]
Abstract
New screen-printed sensor with a boron-doped diamond working electrode (SP/BDDE) was fabricated using a large-area linear antenna microwave chemical deposition vapor system (LA-MWCVD) with a novel precursor composition. It combines the advantages of disposable printed sensors, such as tailored design, low cost, and easy mass production, with excellent electrochemical properties of BDDE, including a wide available potential window, low background currents, chemical resistance, and resistance to passivation. The newly prepared SP/BDDEs were characterized by scanning electron microscopy (SEM) and Raman spectroscopy. Their electrochemical properties were investigated by cyclic voltammetry and electrochemical impedance spectroscopy using inner sphere ([Fe(CN)6]4-/3-) and outer sphere ([Ru(NH3)6]2+/3+) redox probes. Moreover, the applicability of these new sensors was verified by analysis of the anti-inflammatory drug lornoxicam in model and pharmaceutical samples. Using optimized differential pulse voltammetry in Britton-Robinson buffer of pH 3, detection limits for lornoxicam were 9 × 10-8 mol L-1. The oxidation mechanism of lornoxicam was investigated using bulk electrolysis and online electrochemical cell with mass spectrometry; nine distinct reaction steps and corresponding products and intermediates were identified.

Abstract
INTRODUCTION Pain management after open inguinal hernia repair has become an issue that physicians deal with on a daily basis. AIM The purpose of this study was to investigate the analgesic effect of three different regimens of analgesics administered to patients undergoing open inguinal hernia repair. METHODS A total of 259 patients undergoing open inguinal hernia repair were enrolled. Patients were randomly allocated to one of three groups on admission, which would determine the prescribed post-operative analgesic regimen. Patients allocated to group A receiving a combination of 1gr/8hours intravenous (IV) acetaminophen and 50mg/6hours intramuscular (IM) pethidine, patients in group B receiving a combination of 1gr/8hours IV acetaminophen and 40mg/12hours IV parecoxib, while patients of group C received 1gr/8hours IV acetaminophen monotherapy. All patients remained overnight at the hospital and discharged the day after. Analgesic therapy was administered at regular intervals. Pain was evaluated utilizing the numeric rating scale (NRS) at 5 time points: the first assessment was done at 45 minutes, the second at 2 hours, the third at 6 hours, the fourth at 12 hours and the fifth at 24 hours post-administration. The postoperative pain intensities measured by NRS within groups and between groups at each time were analyzed using one-way repeat measured ANOVA and Post Hoc Test-Bonferroni Correlation. RESULTS The analgesic regimens of groups A and B (combination regimens consisting of IV acetaminophen and intramuscular pethidine and IV acetaminophen and IV parecoxib, respectively) were found to be of equivalent efficacy (P-value=1.000). In contrast, patients in group C (acetaminophen monotherapy) had higher NRS scores, compared to both patients in groups A (P-value<0.0001) and B (P-value<0.0001). CONCLUSION The combinations of IV acetaminophen with either intramuscular pethidine or IV parecoxib are superior to IV acetaminophen monotherapy in achieving pain control in patients undergoing open inguinal hernia repair.

Abstract
The aim of the study was to develop a polyester visceral implant modified with a cyclodextrin polymer for the local and prolonged delivery of ropivacaine to reduce post operatory pain. Therefore, we applied a coating of an inguinal mesh with a crosslinked polymer of hydroxypropyl-β-cyclodextrin (HPβCD) whose specific host-guest complex forming properties were expected to improve the adsorption capacity of the implant toward anesthetic, and then to release it within a sustained period. The modification reaction of the textile with cyclodextrin was explored through the study of the influence of the pad/dry/cure process parameters and the resulting implant (PET-CD) was characterized by solid state NMR and SEM. Besides, the inclusion complex between ropivacaine and CD was studied by NMR and capillary electrophoresis in PBS medium. Finally, ropivacaine sorption test showed that a maximum of 30 mg/g of ropivacaine could be adsorbed on the functionalized samples. In dynamic batch tests in PBS at pH 7.4, the release could be observed up to 6h. The cytocompatibility of the PET-CD loaded with ropivacaine was also studied and reached 65% cell vitality after 6 days.

Abstract
INTRODUCTION Non-steroidal anti-inflammatory drugs (NSAIDS) are commonly used for acute pain management. Lornoxicam is a nonselective NSAID for oral and intravenous administration. It has been available for human use since two decades and there is a growing body of evidence supporting its efficacy and tolerability for management of acute pain. AREAS COVERED Public domain literature around the clinical use of lornoxicam for acute pain management has been reviewed. EXPERT OPINION There are a growing number of clinical studies documenting lornoxicam effects for short-term treatment of acute postoperative pain following various surgical procedures. It has in the majority of comparative studies been shown superior as compared to paracetamol, non-inferior compared to other NSAIDs, and commonly similarly effective as standard clinical doses of opioids, but associated with better tolerability. Its effect on other acute pain, for example, headache, back pain, or sports injury is not well studied. Lornoxicam 8 mg twice daily is a seemingly effective and tolerable alternative NSAID for use as sole agent or as part of multimodal analgesia in adults. Available data does however not show any outstanding benefits or special risk. The general precautions with regard to the use of NSAIDs, the potential risks, for example, gastrointestinal bleeding and or cardiovascular side effects must be acknowledged.

Abstract
PURPOSE OF REVIEW Tonsillectomy is a very common procedure, but with risks or challenges, both for the surgeon and anesthesiologist. Many places have considerable experience and expertise with this procedure, and a lot of clinical studies are continuously being presented. RECENT FINDINGS Most preoperative aspects are covered, including indications, preoperative risk assessment, premedication, anesthetic induction and maintenance, as well as recovery function and side-effects; such as bleeding, agitation, pain, nausea and sleep apnea. Controversies exist as to ambulatory versus in-patient care, laryngeal mask airway versus endotracheal intubation, use of local anesthetic infiltration and use of glucocorticoids. SUMMARY Preoperative evaluation should identify increased bleeding risk, potential airway problems, ongoing infection and symptoms of obstructive sleep apnea.Intravenous propofol is most often used for anesthetic induction, although inhalational sevoflurane is a valid alternative. Laryngeal mask airway or endotracheal tube may both be used safely and effectively; the choice will depend upon the routine and experience of the team. Paracetamol and NSAIDs are useful baseline medication for nonopioid multimodal postoperative pain treatment and prophylaxis. Similar with local anesthesia infiltration and dexamethasone medication, although somewhat more disputed. Dexamethasone is also useful for nausea/vomiting prophylaxis, together with ondansetron and also propofol for anesthesia maintenance.
