The Causes of Intraoperative Pain among Elective Caesarean Section Patients under Sub-Arachnoid Block at the Tamale Teaching Hospital

Background: Intraoperative pain is a possible complication of neuraxial anaesthesia for caesarean delivery. Possible causes of intraoperative pain following caesarean section under spinal anaesthesia have been proposed. The potential consequences include inadequate anaesthesia, nerve injury during needle insertion, manipulation of internal organs during surgery, and psychological factors such as anxiety and fear. This study was conducted to assess the causes of intraoperative pain among patients undergoing elective caesarean section under sub-arachnoid block at the Tamale Teaching Hospital. Methods: A descriptive cross-sectional research design was employed in this study. A total of 55 women who have had elective caesarean section under sub-arachnoid block were selected for the study. Data was collected using a structured questionnaire and analysed with the SPSS. Results: Findings from the study showed a high incidence of intraoperative pain among women during elective caesarean section under sub-arachnoid block (96.4%). These were mainly sharp and aching pain. However, the levels of the pain experienced intraoperative were mild (52.7%) and moderate (43.6%). Increased length of time spent during surgery and ineffectiveness of medications/ injections given to prevent pain were the main factors contributing to intraoperative pain among patients during elective caesarean section under sub-arachnoid block. Conclusions: The study found a substantial incidence of intraoperative pain during caesarean delivery. To mitigate intraoperative discomfort and enhance the overall surgical experience for patients having elective CS, it is crucial to address these issues by employing optimised anaesthesia techniques, implementing effective pain management measures, and utilising preoperative psychological therapies.

Magnetic resonance-guided focused ultrasound thalamotomy for essential tremor patients with low skull density ratio: a case-matched analysis.

Skull density ratio (SDR) is the ratio between the mean Hounsfield units of marrow and cortical bone, impacting energy transmission through the skull. Low SDR has been used as an exclusion criterion in major trials of magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy for medication-refractory essential tremor (ET). However, some studies have suggested that patients with low SDR can safely undergo MRgFUS with favorable outcomes. In this case-matched study, we aim to compare the characteristics, sonication parameters, lesion sizes, and clinical outcomes of patients with low SDR vs. patients with high SDR who underwent unilateral MRgFUS thalamotomy for medication-refractory ET. Between March 2016 and April 2023, all patients (n = 270) who underwent unilateral MRgFUS thalamotomy for medication-refractory ET at a single institution were classified as low SDR (<0.40) and high SDR (≥0.40). All clinical and radiological data was prospectively collected and retrospectively analyzed using non-case-matched and 1:1 case-matched methodology. Thirty-one patients had low SDR, and 239 patients had high SDR. Fifty-six patients (28 in each cohort) were included in 1:1 case-matched analysis. There were no significant differences in baseline characteristics between the two groups in both non-case-matched and 1:1 case-matched analyses. In both analyses, compared to patients with high SDR, patients with low SDR required a significantly higher maximum sonication power, energy, and duration, and reached a lower maximum temperature with smaller lesion volumes. In the non-case-matched and case-matched analyses, low SDR patients did not have significantly less tremor control at any postoperative timepoints. However, there was a higher chance of procedure failure in the low SDR group with three patients not obtaining an appropriately sized lesion. In both analyses, imbalance was observed more often in high SDR patients on postoperative day 1 and month 3. ET patients with SDR <0.40 can be safely and effectively treated with MRgFUS, though there may be higher rates of treatment failure and intraoperative discomfort.

Implementation of robot-assisted lymphaticovenous anastomoses in a microsurgical unit

BackgroundNumerous papers have been published evaluating the clinical benefits of robot-assisted microsurgery. In this study, we describe the incorporation of the MUSA-2 robot (Microsure, Eindhoven, The Netherlands) into a plastic surgery unit outside of its development centre. We aimed to assess robot implementation timeframes, areas of future development, and key learning points for centres considering the establishment of a robot-assisted microsurgery service.MethodsWe identified 12 female patients with upper limb lymphoedema secondary to breast cancer treatment, who consented to have a robotic-assisted lymphaticovenous anastomosis (LVA) from September 2022 to March 2023. All patients had at least one robot-assisted LVA. Post operatively, a surgical evaluation of the robot’s performance and of the surgeon’s intraoperative workload was measured. Each patient completed a postoperative Likert scale, which measured their surgical experience.ResultsThe mean robot time per case was 60.25 min. The mean time taken for the first robot-assisted anastomosis was 32 min. The second robot anastomoses was 30% faster than the first, taking a mean of 22.5 min. The average anastomosis had 4.5 sutures placed robotically. Initial mean scores in the workload survey completed by the surgeon were highest for frustration and effort, both reduced with increasing volume of cases. In 91% of cases, physical intraoperative discomfort was reported by the surgeon but completely resolved following repositioning.ConclusionsThe current technology can be readily incorporated into a microsurgical unit. We developed four key learning points from the implementation of robot-assisted LVA in our microsurgical unit.Level of evidence: Level IV, risk/prognostic study

Advantages of robot-assisted PKP under local anesthesia in the treatment of OVCF: a retrospective, non-randomized, controlled, clinical study.

Robot-assisted technology has been widely used in orthopedic surgery, which can provide surgeons with higher accuracy and reduce radiation exposure. In spinal surgery, robots are often used to assist pedicle screw implantation, while there are relatively few studies on robot-assisted percutaneous kyphoplasty (PKP) under local anesthesia. A total of 96 patients with single-segment OVCF who met the inclusion criteria were included in this study. Fifty-six patients underwent robot-assisted PKP and forty patients underwent conventional PKP by the same group of surgeons. Collect the relevant parameters. The puncture time and fluoroscopy times during puncture in the robot group were significantly less than those in the manual group (P < 0.001). The success rate of first puncture in the robot group was 92.5%. PKP under local anesthesia assisted by the new spinal surgical robot effectively reduces the patient's intraoperative discomfort and has a low learning curve.

Evaluation of intraoperative bleeding in shoulder arthroscopy with preoperative injection of epinephrine saline: a retrospective comparative study.

Several studies report the positive effects of epinephrine saline irrigation in shoulder arthroscopy3,4,15,18,22,23. Cardiovascular adverse effects have been described1,2,5,6,7,9,19. The Wide Awake Local Anesthesia No Tourniquet (WALANT) limits bleeding13,16,24,25. The aim of this study is to evaluate the effects of epinephrine saline infiltrations of the shoulder on arthroscopic visual comfort. We carried out a retrospective comparative study composed of 2 groups. We included all patients admitted to the department for a rotator cuff surgery. Our exclusion criteria were any other surgical indication and patient refusal. The protocol consisted in making 3 preoperative shoulder infiltrations of 20 ml of epinephrine saline at 0.005 mg/mL. Injections were performed in all patients in group 1 and no specific treatment was performed in group 2 (control group). Data collection was performed the same way in both groups. The main judgment criterion was the evaluation of the surgeon's overall visual comfort using the Visual Analogue Scale (VAS) at the end of the procedure. We also evaluated the intraoperative discomfort related to bleeding every 15 minutes by an objective scale (the Visual Numeric Rating Scale VNRS), as well as the cumulative bleeding time, operating time, the quantity of irrigation fluid used, the blood pressure at the times of the bleeding, the mean blood pressure during the surgery and the presence of thromboembolic and cardiovascular adverse events. We included 30 patients in group 1 and 30 patients in the control group. The mean VAS value at the end of the intervention is significantly higher in group 1 than in the control group: VAS = 10 in group 1 versus VAS = 5 in group 2 (p<0.0001) (higher is better). We also observed a significant decrease in VNRS between the two groups: VNRS = 0.25 in group 1 versus VNRS = 1,00 in group 2 (p<0.0001) (lower is better). Bleeding time was significantly lower in patients in group 1 (1min 39s) compared to patients in group 2 (9min 57s) (p<0.0001). No significant difference was demonstrated concerning the operating times, the quantity of irrigation fluid used and the blood pressure data of the two groups. No adverse effects were observed. The infiltration of low doses of adrenaline as performed in WALANT procedures seems effective in improving visualization in arthroscopy by reducing the bleeding. It can be a simple, efficient, and cost-effective technique with no iatrogenic risk to improve the surgeon's comfort in arthroscopic procedures.

The burden of performing minimal access surgery: ergonomics survey results from 462 surgeons across Germany, the UK and the USA

This international study aimed to understand, from the perspective of surgeons, their experience of performing minimal access surgery (MAS), to explore causes of discomfort while operating and the impact of poor ergonomics on surgeon welfare and career longevity across different specialties and techniques. A quantitative online survey was conducted in Germany, the UK and the USA from March to April 2019. The survey comprised 17 questions across four categories: demographics, intraoperative discomfort, effects on performance and anticipated consequences. In total, 462 surgeons completed the survey. Overall, 402 (87.0%) surgeons reported experiencing discomfort while operating at least ‘sometimes’. The peak professional performance age was perceived to be 45–49 years by 30.7% of surgeons, 50–54 by 26.4% and older than 55 by 10.1%. 86 (18.6%) surgeons felt it likely they would consider early retirement, of whom 83 were experiencing discomfort. Our findings highlight the continued unmet needs of surgeons performing MAS, with the overwhelming majority experiencing discomfort, frequently in the back, neck and shoulders, and many likely to consider early retirement consequently. Innovative solutions are needed to alleviate this physical burden and, in turn, prevent economic and societal impacts on healthcare systems resulting from MAS limiting surgeon longevity.

A structured exercise to relieve musculoskeletal pain caused by face-down posture after retinal surgery: a randomized controlled trial

Face-down posture after vitrectomy physically burdens patients. Despite being of significant concern for patients, the intraoperative pain and discomfort has not been of great interest to retinal surgeons or researchers. This randomized controlled trial evaluated the effect of a 3-day novel structured exercise on reducing musculoskeletal pain from the face-down posture in 61 participants (31 in the exercise group) who underwent vitrectomy. Among the subjects, the median age was 62 years, 42 were female, 42 had macular holes, and 19 had retinal detachments. Participants in the exercise group received initial education on the exercise and performed three daily active exercise sessions. After the sessions, the exercise group had median numeric pain scores of 2, 1, and 1 at the back neck, shoulder, and lower back, respectively, while the control group had corresponding scores of 5, 3, and 4, respectively. The exercise group reported significantly lower pain scores (P = .003, .039, and .006 for the back neck, shoulder, and lower back, respectively). Application of the structured exercise would alleviate the patients’ position-induced postoperative physical burden, by reducing pain and discomfort.

Removal of nonpalpable etonogestrel implants after fixation with a curved needle—A case series,

ObjectiveTo report our experiences with an extraction technique using a prebent, curved needle placed under deeply located single-rod implants to aid in removal. Study designWe conducted a retrospective case series of all patients who were referred for removal of a deeply located or nonpalpable implant to one single specialized center between 2002 and 2019 by screening the database of the private office for “complex implants removals” or “nonpalpable implant” as a result for consultation. After implant-localization via high-resolution ultrasound, we performed a standard incision along the axis of the rod under local anesthesia. We fixed the rod by insertion of a curved needle directly beneath it piercing it through the tissue to the opposite side of the skin. After dissection of the subcutaneous tissue, we palpated the rod above the needle, grasped and removed it. In case of subfascial or intramuscular locations, we applied retractors and opened the fascia along the axis of the device to attempt removal. ResultsOf 117 referrals, medical records of 95 patients provided sufficient information to be included in our analysis. We could not palpate 81 (85%) devices and questionably palpate 14 (15%) implants. We successfully extracted all implants using this technique with an average removal duration of 30 minutes (SD +/- 6.8). Five (5.3%) patients noted intraoperative discomfort with 3 of them describing transient dysesthesia in the fingers innervated by the median nerve, which disappeared within a maximum of 48 hours. ConclusionFollowing the described protocol, this novel technique reliably facilitates removal of nonpalpable or deeply located etonogestrel implants. ImplicationsThis series of nonpalpable implants, all of which have been removed with the same standardized technique provides evidence that the given protocol permits successful extraction.

Combined Spinal Epidural Anaesthesia Technique with Ketamine Infusion for Emergency Laparotomy of a Known COVID-19 Case at High Altitude of 12000 Feet Above Mean Sea Level

SARS-CoV-2 is a highly infectious virus known to cause severe acute respiratory syndrome in humans known as COVID-19. It is well established that the mode of transmission is through aerosol generation. Since the invasive procedures like endotracheal intubation place the anaesthesiologist and the operating room staff highly exposed to the risk of infection it is prudent to follow regional anaesthesia technique wherever possible. The present case is of a 34-year-old COVID 19 positive male patient who underwent emergency laparotomy in a service hospital of armed forces at 12000 feet above sea level under combined spinal and epidural anaesthesia supplemented with sedation using intravenous infusion of Ketamine. After the attachment of standard ASA monitor and taking in account of baseline readings patient was administered an 18-gauge epidural secured in the T12-L1 level with the catheter was fix at 12 cm on the skin. Sub arachnoid block was administered to the patient using 2.75 ml of 0.5 % Bupivacaine (heavy) and 25 mcg of Fentanyl in L2-L3 space using a 26-gauge spinal needle in sitting position. Once the height of the block was ascertained at T6 level by loss of temperature sensation the surgery commenced. Patient was administered with 3.0 mg of Morphine in epidural space for perioperative analgesia. For allaying intraoperative discomfort patient was sedation infusion of Ketamine of 0.6mg/kg/hr to keep the Ramsay sedation score between 3-4. The intraoperative period was uneventful, and the patient did not require any supplemental analgesia during the surgery. Post operatively the patient was pain free and comfortable with no features of hypopnea, post-operative nausea vomiting and shivering and was shifted to the post-operative care unit in the covid facility of the hospital.

Low Negative Pressure Combined With Supertumescence Microliposuction as a New Method for Repairing Facial Fat Overfilling: A Case Series of 32 Patients.

Face fat overfilling sometimes occurs and is unfortunately very difficult to repair. The aim of this study was to report initial experience of microliposuction with low negative pressure combined with supertumescence (LNPST) in a case series of 32 patients. The LNPST microliposuction was performed in 32 patients aged 22 to 41 years (mean [standard deviation] age, 29.6 [4.9] years) with facial overfilling. Discomfort and bleeding were monitored intraoperatively by 2 independent plastic surgeons, who used a grading system to record the results. All patients were followed-up for hematoma within 1 week postoperatively and for skin numbness and muscle paralysis at 1 week and 3 months postoperatively. In addition, at 6 months postoperatively, patient satisfaction with the postoperative aesthetic effects was analyzed by FACE-Q questionnaire. All patients successfully completed the operation under local anesthesia. The mean intraoperative discomfort and blood-loss scores were 1.69 [0.62] and 1.22 [0.41], respectively. The hematoma score was 1.13 [0.34] within 1 week. Other scores included postoperative skin numbness (1 week, 1.96 [0.62]; 3 months, 1.13 [0.33]) and postoperative muscle paralysis (1 week, 1.22 [0.51]; 3 months, 1.0 [0]). Overall, neither skin necrosis nor serious complications requiring revision surgery occurred. Seventy-two percent of the patients (n = 23) answered the FACE-Q questionnaire and the score was 21.8 (1.7), covering satisfaction with the outcome score into a standard score (81.7 [15.1], from 0 to 100), which verified the high satisfaction rate. LNPST technology is a safe and effective method for repair of facial fat overfilling, with less bleeding, less nerve injury, fewer complications, and high patient satisfaction.

Dexmedetomidine combined with midazolam infusion guided by bispectral index during bronchoscopy.

Conscious sedation guided by bispectral index (BIS) during bronchoscopy has been proved to be a feasible approach. This study aimed to investigate the safety and efficacy of dexmedetomidine combined with midazolam for undergoing conscious sedation during bronchoscopy. The trial was registered prior to patient enrollment at the Chinese Clinical Trial Registry. Patients were randomized into DEX group (dexmedetomidine combined with midazolam) and FEN group (fentanyl combined with midazolam). Bronchoscopy was performed under awake sedation titrated to a BIS level of 60-80. The primary endpoint was the incidence of hypoxia, the secondary endpoint was the incidence of bradycardia and hypotension, effect of sedation including satisfaction degree (VAS) of the operators and patients and patients' willingness to undergo bronchoscopy again. A total of 222 cases in DEX group and 211 cases in FEN group completed the study. The incidence of hypoxia and tachycardia in DEX group was lower than that in FEN group (8.1% vs 14.7%, 10.4% vs 19.0%, p<0.05), and the incidence of hypotension and bradycardia in DEX group was higher than that in FEN group (6.8% vs 0, 15.3% vs 8.1%, p<0.05). Midazolam dosage was significantly lower in the DEX group than in the FEN group, and the duration of surgery was significantly longer in the DEX group. The differences in intraoperative discomfort of VAS score, satisfaction VAS score, and willingness rate to undergo bronchoscopy again were not statistically significant between the two groups. In addition, the proportion of "procedural interference by patient movement" in DEX group was higher than that in FEN group. The conscious sedation regimen of dexmedetomidine combined with midazolam monitored by BIS is considered to be safe and effective during bronchoscopy. The occurrence of hypoxia and tachycardia was less, and the fluctuation of blood pressure and heart rate was mild, but the proportion of bradycardia in dexmedetomidine group was higher than that in fentanyl combined with midazolam group.

Radiofrequency VS Cold Surgery to Treat Oral Papillomatous Lesions.

Introduction:The aim of this study is to analyse different surgery (radio frequency and cold instrumentation) of oral benign papillomatous lesions.Materials and Methods:A retrospective study was carried out in our section of Otorhinolaryngology from 2014 to 2018. 112 patients with oral benign papillomatous lesions were enrolled and divided into 2 groups. Group A of 62 patients treated with excision of lesions using radio frequency using a bipolar coagulation electrode (CelonLabENT). Group B of 50 patients treated with excision of the lesion using traditional cold instruments (scalpel and surgical forceps). All patients were evaluated for intraoperative bleeding, discomfort and recurrence rate. Results:112 patients (of which 37 males and 75 females) with mean age 32.9 ranged from 10 to 61 years. The HPV types associated with oral benign papillomatous lesions were HPV 6 (17%), 11 (23,3%), 13 (10,7%), 32 (34%), 2 (10%) and 57 (5%). There are no statistically significant differents among patients operated with radio frequency (Group A) and cold instrumentation (Group B) regarding intraoperative bleeding (P= 0.08), recurrence rate after 1 year from surgery (P=1), intraoperative discomfort (P=0.7) and postoperative discomfort (P=0.6).Conclusion:Radiofrequencies and surgery with scalpel and surgical forceps are equal valid methods for the treatment of benign papillomatous.

Fentanyl compared to buprenorphine for atrial fibrillation ablation analgesia and sedation: a retrospective cross-sectional study

BackgroundThe effects of general anesthesia with deep sedation and conscious sedation have been compared for sedation management in the perioperative period for radiofrequency catheter ablation of the heart to treat atrial fibrillation. However, there is no consensus as to which drug to use for conscious sedation. This study aimed to investigate analgesic and sedative drugs suitable for perioperative ablation.MethodsWe retrospectively examined 93 patients who underwent atrial fibrillation ablation at Kariya Toyoda General Hospital between December 2017 and April 2019 and investigated differences in the outcomes, such as depth of sedation and postoperative adverse events between the buprenorphine hydrochloride (n = 46) and fentanyl citrate (n = 47) groups.ResultsThe depth of sedation was similar between the two groups, without significant between-group differences in postoperative vomiting. The number of additional injections of thiamylal sodium to manage discomfort and pain during ablation were significantly lower in the fentanyl group. Additionally, the cumulative area product, cumulative total air kerma, 1-year postoperative atrial fibrillation recurrence rate, and postoperative complications were not significantly different between the two groups.ConclusionsAlthough there were no significant differences in the efficacy or safety between buprenorphine hydrochloride and fentanyl citrate as analgesics used during atrial fibrillation ablation, intraoperative body movements and patient discomfort could be reduced to a greater extent with the use of fentanyl.

Role of CO2 Laser in the Management of Symptomatic Hypertrophy of Inferior Nasal Turbinates.

The aim of this study was to evaluate the efficacy of CO2 laser ablation in the management of symptomatic hypertrophied inferior nasal turbinates. This prospective observational study was carried out on 53 patients with symptomatic ITH refractory to medical management in the Department of Otorhinolaryngology and Head and Neck Surgery, SMHS Hospital, Srinagar, J&K from January 2017 to June 2018 after obtaining ethical clearance. The pre and postoperative subjective assessment of the nasal obstruction included nasal obstruction symptom evaluation scale (NOSE) and the visual analogue scale (VAS). Lund and Kennedy endoscopic scoring was used to assess postoperative intranasal crusting and tissue healing. Postoperative pain was evaluated using VAS. All patients underwent CO2 laser spot ablation of hypertrophic inferior turbinates under local anesthesia in an outpatient setting. The patients were followed up at 2weeks, 1month and 3months postoperatively. The VAS score for nasal obstruction improved from preop score of 6.05 (± 2.1) to 3.0 (± 1.01), 2.01 (± 0.90), 1.18 (± 0.40) at 2weeks, 1month and 3months respectively in the postop period and the NOSE score also improved from preop score of 64.90 (± 13.29) to post-operative NOSE score of 18.96 (± 9.53) at 2weeks, 9.81 (± 7.33) at 1month and 5.09 (± 4.28) at 3months. Difference between preoperative and postoperative NOSE and VAS scores was statistically significant (p < 0.05). There was minimal postoperative pain and intranasal crusting. Postoperative tissue healing was also good. CO2 laser turbinoplasty is a safe and effective way of improving nasal flow. It offers more precision, gentleness, control and less intraoperative discomfort. CO2 laser turbinoplasty meets all of the criteria for an ideal method for the treatment of nasal obstruction secondary to inferior turbinate hypertrophy with improvement of quality of life and reducing the risk of medical morbidity.

Anesthetic efficacy and safety of 2% lidocaine hydrochloride with 1:100,000 adrenaline and 4% articaine hydrochloride with 1:100,000 adrenaline as a single buccal injection in the extraction of maxillary premolars for orthodontic purposes.

BackgroundPalatal injection of local anesthetics is the most painful injection. To obviate the need for palatal injections, local anesthetic agents with diffusibility are being investigated. Hence the present study was designed to analyze the anesthetic efficacy of 2% lidocaine hydrochloride (HCl) with 1:100,000 adrenaline and 4% articaine hydrochloride (HCl) with 1:100,000 adrenaline using single buccal infiltration for the extraction of maxillary premolars.MethodsA prospective, double-blind, crossover, randomized clinical study was performed on 60 consecutive systemically healthy patients with an age range of 15-30 years, requiring extraction of asymptomatic bilateral maxillary premolars for orthodontic purposes. They received 1ml buccal infiltration of 4% articaine HCl with 1:100,000 adrenaline on one side and 2% lidocaine HCl with 1:100,000 adrenaline on the other side. The extraction procedure on either side was scheduled 14 days apart. Parameters assessed were the time of onset of anesthesia, intraoperative discomfort, hemodynamic parameters, and the duration of analgesia. Analysis of the data was done using the Mann-Whitney test, the Wilcoxon test, the Kruskal-Wallis ANOVA test, and the chi-square test. Statistical significance was established at P < 0.05.ResultsArticaine showed a faster time of onset and longer duration of analgesia than lidocaine. However, the difference in the intraoperative discomfort and hemodynamic parameters was statistically insignificant.ConclusionWithin the limitations of the study, it can be concluded that the extraction of maxillary premolars can be performed with a single buccal infiltration of 2% lidocaine HCl with 1:100,000 adrenaline, which is one of the most commonly used local anesthetic agent.

Effect of Predictive Nursing on Preventing from Bone Cement Implantation Syndrome in Hemiarthroplasty

This study is to explore the effect of predictive nursing mode on preventing from bone cement implantation syndrome in hemiarthroplasty. 55 patients who were performed with bone cement hemiarthroplasty in our hospital from January 2018 to December 2018 were selected. These patients were divided into conventional group (n=25) and predictive nursing mode group (n=30) according to nursing modes. Then the systolic pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) and oxyhemoglobin saturation (SpO₂) of the two groups of patients were compared 10min before injection of bone cement (T1), at the time of implantation of bone cement (T2), and 10min after injection of bone cement respectively (T3). The occurrence situation of respiratory distress, arrhythmia, dizziness, chest distress, panic, nausea, vomiting and shock for the two groups of patients in the surgery were compared. There was no significant difference for the comparison of the data including age, cardiac function, etc. of the patients between the conventional group and predictive nursing mode group. However, SBP and DBP of the intervention group at the time of T1, T2 and T3 were higher than that of the conventional group (P<0.05). Additionally, HR and SpO₂ of the intervention group at the time of T1, T2 and T3 were higher than that of the conventional group (P<0.05). As for the comparison of the evaluation indexes of bone cement for the two groups of patients in the surgery, the occurrence situation of hypotension, hyoxemia and RDS for the intervention group were apparently lower than that for the conventional group (P<0.05). As for the comparison of the intraoperative discomfort for the two groups of patients, the occurrence situation of dizziness, chest distress, panic, vomiting, nausea and shock of the intervention group were lower than that of the conventional group. The predictive nursing mode can be used for early intervention so as to relieve and avoid the occurrence of bone cement implantation syndrome in hemiarthroplasty, therefore it is worthy of being promoted for application. Suspected BCIS should be treated with aggressive resuscitation and supportive care. Prevention of BCIS includes identification of high-risk patients, preoperatively optimizing patient risk factors and comorbidities, and good communication with the surgical team.

Comparative study of hyperbaric bupivacaine 0.5% versus hyperbaric bupivacaine 0.5% and fentanyl in spinal anaesthesia for lower abdominal and lower extremity surgeries

The study was conducted to compare the differences in the onset, duration of action of intrathecal hyperbaric bupivacaine 0.5% (group-I) versus intrathecal hyperbaric bupivacaine 0.5% and fentanyl 25 mg (group-II) in spinal anaesthesia in lower abdominal and lower extremity surgeries. The combination of bupivacaine and fentanyl helps anaesthesiologist to alleviate intraoperative discomfort by providing better analgesia to the patients without prolonging recovery. 100 patients belonging to ASA grade-I and II of both the sexes (n=50 in each group) were randomly selected for the study. The time of onset of sensory and motor block, duration of analgesia, 2-segment regression, intraoperative discomfort, time to micturition, visual analogue score, post operative analgesic requirements were assessed. The time of onset of sensory and motor block were significantly longer in group-II than group-I (P

Short versus longer implants with osteotome sinus floor elevation for moderately atrophic posterior maxillae: A 1-year randomized clinical trial.

To compare the clinical, radiographic outcomes and patient satisfaction of short-6-mm implants and longer implants combined with osteotome sinus floor elevation (OSFE). Two hundred and twenty-five patients with 225 implants were included and randomly assigned into three groups (each group: 75 implants) using randomizing table method: group 6mm (6mm implants alone), group 8mm+O (8mm implants+OSFE) and group 10mm+O (10mm implants+OSFE). Outcomes measures were as follows: implant survival, complication, resonance frequency analysis measurement, surgical time, bleeding on probing (BOP), pocket probing depth (PPD), modified plaque index (mPI), marginal bone loss (MBL) and patient satisfaction. The dropout rate was 3.6% at 1year. Implant survival rates were 96%, 100% and 100% in group 6mm, group 8mm+O and group 10mm+O, respectively. In group 6mm, the survival rates of implants with diameter of 4.1mm were 90% (27/30), while the survival rates of implants with diameter of 4.8mm were 100% (42/42). The surgical time (min) in group 6mm was significantly shorter than those in group 8mm+O and group 10mm+O (13.6±2.2, 19.4±3.7 and 18.3±4.3, respectively, p=0.03). No significant differences in ISQ values, BOP, PPD, mPI and MBL were found among three groups. Significant higher value of intra-operative discomfort was found in group 6mm (p=0.02). All treatment options provided acceptable clinical and radiographic results up to 1year after loading. The current 1-year results must be confirmed by longer follow-ups of at least 5years.

Could Music Minimize Discomfort and Pain During Office-Based ENT Surgery?

Background Video-assisted endoscopic radiofrequency inferior turbinate volume reduction (RFVTR) is one of the most common surgical therapies for inferior turbinate hypertrophy (ITH). Despite all the technical and surgical advancement, it is advisable to reduce as low as possible the intraoperative discomfort. The aim of this study is to evaluate the role of music in reducing patient discomfort during RFVTR. Materials and Methods Twenty-three patients with chronic nasal obstruction due to ITH and candidate to RFVTR are included. Before the procedure each patient filled in a completed Italian version of the state anxiety questionnaire (State-Trait Anxiety Inventory), SNOT 22 questionnaire, VAS, and chose their favourite music to be played during RFVTR. All patients evaluate the intraoperative discomfort with a visual analog scale (VAS) and for each patient, vital parameters such as blood pressure and heart rate were recorded 15 minutes before the procedure, during and after RFVTR. Results The intraoperative VAS scores during listening to music (5.7 ± 2.42 vs 6.7 ± 1.97; p< 0.05) were significantly lower, such as systolic BP (133.5 ±17.2 vs 136.78 ±16.8; p< 0.05) and heat rate (80.3 ±14.9 vs 81.7 ±15.5; p NS). During our survey, most of the patients preferred listening to classical music and none preferred rock music. No correlation was found between STAI 1-2 and intraoperative surgical discomfort evaluated both with VAS and cardiac parameters (systolic BP and HR). Conclusions Music can be useful as a complementary method to control anxiety and reduce perception of pain in an office-based procedure, such as the RFVTR. The patient is more relaxed and experiences less discomfort; thus the surgeon and nurse can work with more confidence.
