Pars plana vitrectomy (PPV) combined with intraocular tamponade surgery is one of the main surgical methods for treating retinal detachment. Due to the use of filling substances, patients need to maintain specific postures after the operation to promote retinal reattachment and reduce the occurrence of complications. Currently, during the process of performing postural management for such surgical patients, there are problems such as low compliance and insufficient monitoring and management. Clinical medical staff have actively explored ways to improve the quality of positioning management, but no corresponding norms and consensus have been formed. The standards implemented by different places are closely related to the degree of medical experience. The evaluation of the performance of the patient's position by the medical care mainly relies on the patient's self-report or the nurse's inspection record, which lacks continuity and accuracy. In the future, it is necessary to further promote the development and transformation of auxiliary tools, implement scientific monitoring and management of patients with the help of artificial intelligence, formulate individualized plans and dynamically adjust them according to the patient's condition, and ensure the effect and improve patient satisfaction.
Objective To evaluate the feasibil ity and effectiveness of percutaneous kyphoplasty in hyperextension position for treatment of stage II or III Kümmell disease. Methods Between May 2003 and February 2009, 17 patients with Kümmell disease (6 at stage II, 11 at stage III) were treated with percutaneous kyphoplasty in hyperextension position. There were 5 males and 12 females with an average age of 71 years (range, 55-85 years). The involved vertebral bodies were T10 in 1 case, T11 in 3 cases, T12 in 7 cases, L1 in 4 cases, L2 in 1 case, and T12, L1 in 1 case by X-ray, CT, and MRI examinations. The effectiveness was determined by the visual analogue scale (VAS) and the Oswestry Disabil ity Index (ODI). The height and the kyphotic Cobb angle of the involved vertebral body were measured pre- and postoperatively. Results The operation was successfully completed in all the patients, and the incisions healed by first intention. Pain was alleviated or eliminated within 48 hours after operation; no spinal nerves injury or pulmonary embolism occurred. One patient had cement leakage to the adjacent disc, who did not manifest any cl inical symptoms. Thirteen patients were followed up 24 to 56 months (mean, 32 months). The VAS score, ODI, anterior and medial vertebral height, kyphotic Cobb angle of involved vertebral body were improved significantly at 1 week after operation and at last follow-up (P lt; 0.05), there was no significant difference between at 1 week after operation and at last follow-up (P gt; 0.05). Adjacent vertebral fracture occurred in 1 patient at 6 months after operation and was cured after percutaneous kyphoplasty. Conclusion Percutaneous kyphoplasty in hyperextension position for treatment of stage II or III Kümmell disease can rel ieve back pain, improve viabil ity, decrease Cobb angle, and retain the vertebral body height and spinal alignment. The general condition of the patient is needed to be evaluated and the operation indication should be controlled strictly.
ObjectiveTo compare the effectiveness of proximal femoral nail anti-rotation (PFNA) between in the supine "scissors" position and in the lithotomy position for treating femoral intertrochanteric fractures of old patients. MethodsA retrospective study was performed on 58 patients with femoral intertrochanteric fractures treated with PFNA between January 2013 and January 2015. Fracture was treated with PFNA in the lithotomy position in 28 cases (group A) and in the supine "scissors" position in 30 cases (group B). There was no significant difference in gender, age, side, cause of injury, fracture type, and interval from injury to operation between 2 groups (P>0.05). The incision length, operation time, perspective times, intraoperative blood loss, complications, and fracture healing time were recorded; Harris hip score was used to access the effectiveness. ResultsThe wound healed by first intention without infection, pressure sores, deep vein thrombosis of lower extremity, and other complications. There was no significant difference in incision length between 2 groups (t=1.313, P=0.212). Group B was significantly better than group A in operation time, perspective times, and intraoperative blood loss (P<0.05). All patients were followed up 10-31 months (mean, 15.3 months). Stretch injury at normal side and perineal discomfort occurred in 1 case and 5 cases of group A respectively, and no nonunion and other complications was observed in the other patients. There was no significant difference in fracture healing time and Harris hip score at last follow-up between 2 groups (P>0.05). ConclusionPFNA in the supine "scissors" position has exact effectiveness and advantages of shorter operation time, less intraoperative blood loss, less perspective times, and fewer complications.
ObjectiveTo compare and observe the curative effect of different body positions after pars plana vitrectomy (PPV) combined with inert gas filling for rhegmatogenous retinal detachment (RRD). MethodsA retrospective clinical study. From October 2019 to September 2021, 192 eyes of 192 RRD patients who were diagnosed and received PPV combined with inert gas filling in Qingdao Eye Hospital of Shandong First Medical University were included in the study. Best corrected visual acuity (BCVA), intraocular pressure, ultra-wide-angle fundus photography, optical coherence tomography, and B-mode ultrasonography were performed in all affected eyes. The BCVA examination was performed using a standard logarithmic visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. According to the post-operative position requirements, the affected eyes were divided into the face-down positioning group and the adjustable positioning group, with 97 eyes in 97 patients and 95 eyes in 95 patients, respectively. Age (Z=0.804), course of disease (Z=－0.490), eye type (χ2=0.175), logMAR BCVA (Z=－0.895), intraocular pressure (Z=0.178), lens status (χ2=1.090), number of detached clocks (Z=0.301) and macular involvement (χ2=0.219), number of holes (Z=－1.051) and number of lower holes (χ2=0.619) were compared, there was no significant difference (P＞0.05). The gender composition ratio was compared, and the difference was statistically significant (χ2=5.341, P＜0.05). The follow-up time after surgery was more than 3 months. The retinal reattachment rate in one operation, the improvement of BCVA and the incidence of complications were observed. The independent sample Mann-Whitney test was used for the comparison of continuous variables between groups; the χ2 test was used for the comparison of categorical variables. ResultsIn the face-down positioning group and the adjustable positioning group, retinal reattachment in one operation was performed in 92 (94.8%, 92/97) and 89 (93.7%, 89/95) eyes, respectively; logMAR BCVA was 0.45±0.34, 0.41±0.21. There was no significant difference in the retinal reattachment rate in one operation (χ2=0.120, P=0.729) and logMAR BCVA (Z=－0.815, P=0.416) between the two groups. After surgery, the intraocular pressure increased in 11 (11.3%, 11/97) and 5 (5.3%, 5/95) eyes in the face-down positioning group and the adjustable positioning group, respectively; the secondary epimacular membrane was 2 (2.1%, 2/97), 3 (3.2%, 3/95) eyes. There was no significant difference in the incidence of elevated intraocular pressure and secondary epimacular membrane between the two groups after surgery (χ2=2.320, 0.227; P=0.128, 0.634). ConclusionIt is safe and effective to adopt adjustable positioning after PPV combined with inert gas filling for RRD, which is equivalent to the effect of face-down positioning.
Objective To investigate the changes in spinal-pelvic sagittal parameters from preoperative standing to prone position in old traumatic spinal fractures with kyphosis. Methods The clinical data of 36 patients admitted between December 2016 and June 2021 for surgical treatment of old traumatic spinal fractures with kyphosis, including 7 males and 29 females, aged from 50 to 79 years (mean, 63.9 years), were retrospectively analyzed. Lesion segments included 2 cases of T11, 12 cases of T12, 2 cases of T11, 12, 4 cases of T12 and L1, 12 cases of L1, 2 cases of L2, 1 case of L2, 3, and 1 case of L3. The disease duration ranged from 4 to 120 months, with an average of 19.6 months. Surgical procedures included Smith-Petersen osteotomy in 4 cases, Ponte osteotomy in 6 cases, pedicle subtraction osteotomy in 2 cases, and improved fourth level osteotomy in 18 cases; the remaining 6 cases were not osteotomized. The bone mineral density ranged from −3.0 to 0.5 T, with a mean of −1.62 T. The spinal-pelvic sagittal parameters from preoperative standing to prone positions were measured, including local kyphosis Cobb angle (LKCA), thoracic kyphosis (TK), lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), and PI and LL mismatch (PI-LL). The kyphotic flexibility=(preoperative standing LKCA−preoperative prone LKCA)/preoperative standing LKCA×100%. Spinal-pelvic sagittal parameters were compared between standing position and prone position before operation, and Pearson correlation was used to judge the correlation between the parameters of standing position and prone position before operation. ResultsWhen the position changed from standing to prone, LKCA and TK decreased significantly (P<0.05), while SS, LL, PT, and PI-LL had no significant difference (P>0.05). Pearson correlation analysis showed that LL was significantly correlated with SS and PI-LL in both standing and prone positions (P<0.05), and the correlation strength between LL and SS in prone position was higher than that in standing position. In the standing position, LKCA was significantly correlated with SS and PT (P<0.05). However, when the position changed from standing to prone, the correlation between LKCA and SS and PT disappeared, while PT and PI-LL was positive correlation (P<0.05). The kyphotic flexibility was 25.13%-78.79%, with an average of 33.85%. Conclusion For the patients of old traumatic spinal fractures with kyphosis, the preoperative LKCA and TK decrease significantly from standing position to prone position, and the correlation between spinal and pelvic parameters also changed, which should be taken into account in the formulation of preoperative surgical plan.
ObjectiveTo introduce a self-designed adjustable operation frame and explore the feasibility and safety in the treatment of severe kyphosis secondary to ankylosing spondylitis with posterior osteotomy.MethodsBetween March 2016 and May 2018, 7 cases of severe kyphosis secondary to ankylosing spondylitis were treated with posterior osteotomy using self-designed adjustable operation frame with prone position. There were 5 males and 2 females with an average age of 49.4 years (range, 40-55 years). The disease duration was 10-21 years (mean, 16.7 years). The apical vertebrae of kyphosis were located at T11 in 2 cases, T12 in 1 case, L1 in 1 case, and L2 in 3 cases. Among the 7 cases, 2 were classified as typeⅠ, 4 as type ⅡB, and 1 as type ⅢA according to 301 classification system. There was no neurological deficit of all cases; but 1 case suffered bilateral hip joints ankylosed in non-functional position. The parameters of chin-brow vertical angle (CBVA), global kyphosis (GK), thoracolumbar kyphosis (TLK), lumbar lordosis (LL), sagittal vertical axis (SVA) were measured; and the operation time, the intraoperative blood loss, and the complications were also collected and analyzed.ResultsAll operations completed successfully. The operation time was 310-545 minutes (mean, 409.7 minutes) and the intraoperative blood loss was 1 500-2 500 mL (mean, 1 642.9 mL). There were 2 cases treated with one-level osteotomy of sagittal translation, 1 case of radiculopathy symptom of L3, and 3 cases of tension of abdominal skin. All patients were followed up 20-35 months (mean, 27.9 months). There were significant differences in CBVA, GK, TLK, LL, and SVA between pre- and post-operation (P<0.05); but no significant difference between 1 week after operation and last follow-up (P>0.05). All the osteotomies and bone grafts fused well and no complications of loosening and breakage of internal fixator occurred during the follow-up.ConclusionIn the posterior osteotomy for correction of severe kyphosis secondary to ankylosing spondylitis, the self-designed adjustable operation frame is convenient for the patient to be placed in prone position. It is safe, feasible, and effective to perform osteotomy correction with the aid of the self-designed adjustable operation frame.
ObjectiveTo systematically review the efficacy of different positions on the clinical outcomes of percutaneous nephrolithotomy (PCNL). MethodsThe PubMed, Web of Science, EBSCO, Cochrane Library, Embase, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from January 2014 to April 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies, a network meta-analysis was conducted using Stata 18.0 software. ResultsA total of 54 RCTs involving 5 092 patients and 7 different positions were included. The results of the best probability ranking showed that for positioning time, the split-leg prone position required the shortest time, while the traditional prone position required the longest. For access establishment time, the recumbent lithotomy position had the shortest duration, and the traditional prone position the longest. Intraoperative blood loss was lowest in the supine position and highest in the traditional prone position. Surgical duration was shortest for the recumbent lithotomy position and longest for the traditional prone position. Postoperative hospital stay was shortest for the supine position and longest for the traditional prone position. Complication rates were lowest for the oblique supine position and highest for the traditional prone position. Stone clearance rates were highest for the modified curved prone position and lowest for the traditional prone position. Conclusion Current evidence shows that different body positions have different clinical effects on percutaneous nephrolithotomy. The recumbent lithotomy position may optimize access establishment and surgical duration, while the supine position offers advantages in reducing intraoperative blood loss and shortening postoperative hospitalization. The split-leg prone position minimizes positioning time, the oblique supine position lowers complication rates, and the modified curved prone position maximizes stone clearance. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo investigate the effect of posture nursing by specially-assigned person and psychological nursing on patients after vitrectomy combined with intraocular silicone oil tamponade. MethodsFrom February 2012 to February 2013, traditional nursing method or posture nursing by specially-assigned person and psychological nursing was carried out respectively for 140 patients who had undergone vitrectomy and intraocular silicone oil tamponade. Adverse effects and retina reattachment effect were compared between the two nursing methods. ResultsAdverse effects after the surgery were significantly fewer in the experimental group than in the control group (P<0.05). The number of patients with retina reattachment in the experimental group was significantly higher than that in the control group (P<0.05). ConclusionPosture nursing by specially-assigned person and psychological nursing reduce postoperative adverse consequences significantly, and achieve the expected operative effect.
