Abstract
BACKGROUND It is well-established that maintaining stable intraocular pressure (IOP) within the normal range during ophthalmic surgery is important. Esketamine is a commonly used drug in pediatric general anesthesia due to its good analgesic and sedative effects. However, its application in ophthalmic surgery is limited because it can increase IOP. The effect of esketamine combined with other common anesthetics on IOP has been underinvestigated. This study aimed to investigate the effect of different doses of esketamine combined with propofol and sufentanil on IOP during intravenous induction of general anesthesia for pediatric strabismus surgery. METHODS A total of 181 children with strabismus undergoing unilateral eye surgery under general anesthesia were recruited. Intravenous induction included the use of sufentanil 0.1 µg/kg, propofol 3 mg/kg, and esketamine. Base on the dosage of esketamine, the patients were randomly allocated into three groups: esketamine low (EL) group with 0.25 mg/kg (n = 62), esketamine high (EH) group with 0.5 mg/kg (n = 60), and normal saline (NS) group (n = 59). Hemodynamic parameters, respiratory parameters, and IOP of the non-surgical eye were recorded and compared among the three groups at different time points: before induction (T0), 1 min after induction but before laryngeal mask insertion (T1), immediately after laryngeal mask insertion (T2), and 2 min after laryngeal mask insertion (T3). RESULTS There were no significant differences in age, gender, body mass index (BMI), and respiratory parameters among the three groups at T0. The IOP at T1, T2, and T3 was lower than that at T0 in all three groups. The EH group (12.6 ± 1.6 mmHg) had a significantly higher IOP than the EL group (12.0 ± 1.6 mmHg) and the NS group (11.6 ± 1.7 mmHg) at T1. However, no difference was found between the EL and NS groups at any time point. Systolic blood pressure (SBP) and heart rate (HR) at T1, T2, and T3 were lower than at baseline, and SBP and HR were higher at T2 than at T1. Additionally, the EH group had a significantly higher HR at T1 than the other two groups. There was no significant difference in diastolic blood pressure (DBP) among the three groups at any time point. CONCLUSION Propofol combined with sufentanil significantly decreased IOP during the induction of general anesthesia. Although a dose of 0.5 mg/kg esketamine elevated IOP compared to the low-dose and control groups after induction, the IOP remained lower than baseline. 0.25 mg/kg esketamine combined with propofol and sufentanil had little effect on IOP. Therefore, we advocate that a maximum dose of 0.5 mg/kg esketamine combined with propofol and sufentanil will not elevate IOP compared to baseline in pediatric strabismus surgery.

Abstract
AIM Intraocular pressure (IOP) may decrease or increase during general anesthesia, depending on various factors. This study aimed to investigate the effects of the level of provider training period on post-intubation IOP values and hemodynamic response. METHODS This study was a cross-sectional observational study. Before inclusion in the study, informed consent was obtained from all participants. The study was approved by the local ethical committee. The study included 120 adult patients, both sexes, aged between 18 and 65, with physical statuses according to the American Society of Anesthesiologists (ASA) I or II, Mallampati score I. The research included 120 anesthesiologist resident doctors who received their training in our clinic. In this study, anesthesiology resident doctors were divided into three separate seniority groups (group 1, less than one-year residents in anesthesiology who had performed fewer than 10 intubations; group 2, one- to three-year residents; and group 3, more than three-year residents). After receiving a standard intravenous induction, direct laryngoscopy and endotracheal intubation techniques were performed. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and IOP were measured and recorded before pre-induction (T1), the first minute after induction (T2), and the first minute after laryngoscopy and intubation (T3). RESULTS There was no statistically significant difference (p > 0.05) between groups in the values of IOP, SBP, DBP, and HR measured at T1, T2, and T3. Measurements at T1, T2, and T3 were similar in all three groups. Comparisons within the groups revealed that IOP values at all measurement times (T1, T2, and T3) were different from each other in less than three-year resident groups. This difference was statistically significant (p < 0.001). The measurement values at T2 were the lowest and T3 were the highest in less than three-year resident groups. There was a significant increase in IOP after endotracheal intubation (T3) compared to baseline levels (T1) in less than three-year resident groups. IOP values at T2 were also significantly lower than the values at T1 and T3 (p < 0.001) in the more than three-year resident group (group 3). However, when we compared IOP measurements at T1 and T3 among themselves in the more than three-year resident group, no significant difference was found (p > 0.05). CONCLUSION This study showed that endotracheal intubation in general anesthesia practice is performed most effectively by resident doctors with more than three years of anesthesiology training, without changing the IOP value.

Effects of Positive End-Expiratory Pressure on Intraocular Pressure during One-Lung Ventilation in the Lateral Decubitus Position-A Prospective Randomized Trial. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58070940. [PMID: 35888659 PMCID: PMC9318682 DOI: 10.3390/medicina58070940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Revised: 07/13/2022] [Accepted: 07/13/2022] [Indexed: 11/17/2022]
Abstract
Background and Objectives: The effect of positive end-expiratory pressure (PEEP) on intraocular pressure (IOP) is debatable. There have been no studies investigating the effects of PEEP on IOP during one-lung ventilation (OLV). We aimed to investigate the effects of PEEP on IOP in patients undergoing OLV for video-assisted thoracoscopic surgery (VATs). Materials and Methods: Fifty-two patients undergoing VATs were divided into a zero-PEEP (ZEEP) and a 6 cmH2O of PEEP (PEEP) groups. IOP, ocular perfusion pressure (OPP), and respiratory and hemodynamic parameters were measured before induction (T1), immediately following endotracheal intubation (T2), 30 min (T3) and 60 min (T4) after a position change to the lateral decubitus position (LDP) and OLV, and 10 min following two-lung ventilation near the end of the surgery (T5). Results: There was no significant difference in IOP and OPP between the two groups. The IOP of the dependent eye was significantly higher than that of the non-dependent eye during LDP in both groups. Peak inspiratory pressure was significantly higher in the PEEP group than in the ZEEP group at T3-T5. Dynamic compliance was significantly higher in the PEEP group than in the ZEEP group at T2-T5. The ratio of arterial oxygen partial pressure to fractional inspired oxygen was significantly higher in the PEEP group than in the ZEEP group at T4. Conclusions: Applying 6 cmH2O of PEEP did not increase IOP but enhanced dynamic compliance and oxygenation during OLV. These results suggest that 6 cmH2O of PEEP can be safely applied during OLV in LDP.

Abstract
PURPOSE To investigate the agreement between the intraocular pressure (IOP) measurements in the awake condition and under different stages of general inhalational anesthesia using sevoflurane in both glaucomatous and normal children. METHODS A prospective study was performed on 43 glaucomatous children and 30 age-matched controls. Baseline IOP of one eye was measured immediately before general anesthesia using Perkins tonometer and then re-measured under light, intermediate, and deep anesthesia, and then after intubation. Depth of anesthesia was determined using bispectral index pediatric sensor. The agreement between the IOP measurements before and during different stages of anesthesia was analyzed using Bland-Altman plots. Systematic and proportionate deviations between the IOP measurements were analyzed. RESULTS The mean age was 58.6 ± 41.99 months. The mean IOP was significantly lower at all stages of anesthesia in both groups. The coefficient of variation was over 20% in all measurements under anesthesia. For all IOP measurements during anesthesia, the limits of agreement were > 7 mmHg difference in the control group and > 20 mmHg in the glaucomatous group. The best agreement was with the IOP measurement after intubation (mean limit of agreement of -1.4 mmHg, 1.96 s range, -8.8-6 mm Hg) in the control group and with the IOP measurement under intermediate anesthesia (mean limit of agreement of -4.2 mmHg, 1.96 s range, -15.1-6.8 mm Hg) in the glaucomatous group. CONCLUSIONS Inhalational anesthesia has variable effects on IOP measurement at all stages of anesthesia. Caution should be taken when extrapolating the true IOP from these measurements.

Abstract
PURPOSE To evaluate the safety and efficacy of non-penetrating deep sclerectomy with a collagen implant versus trabeculectomy in primary congenital glaucoma. SUBJECTS AND METHODS This was a retrospective interventional comparative non-randomized clinical study that included 80 eyes of 80 children presenting with primary congenital glaucoma under the age of 3 years. Forty eyes have undergone non-penetrating deep sclerectomy (NPDS) and the other 40 eyes have undergone penetrating trabeculectomy. The main outcome measure was the reduction in intraocular pressure (IOP). Secondary outcomes included percentage of patients with complete and qualified success, need for topical antiglaucoma medications, rate of complications, and need for further interventions. Complete success of the surgical outcome was considered an IOP ≤16 mmHg with no antiglaucoma medications. Qualified success was considered an IOP ≤16 mmHg using antiglaucoma medications. RESULTS The mean preoperative IOP was 27.4 ± 6.9 and 28.5 ± 6.6 mmHg in NPDS and trabeculectomy groups, respectively (p = 0.175). At the end of the follow-up period, the mean IOP was 11.2 ± 4.5 and 11.1 ± 3.4 mmHg with a mean reduction of 16.2 and 17.4 mmHg in NPDS and trabeculectomy groups, respectively. At the end of the follow-up period, ie at 36 months postoperative, the complete success rate was 60% (24 eyes) versus 57.5% (23 eyes), the qualified success rate was 25% (10 eyes) versus 25% (10 eyes), the overall success rate was 85% (34 eyes) versus 82.5% (33 eyes), and the rate of failure was 15% (6 eyes) versus 17.5% (7 eyes) in NPDS and trabeculectomy groups, respectively (p = 0.952). Eight cases (20%) of the trabeculectomy group had shallow anterior chamber. None of the NPDS group cases suffered from shallow anterior chamber. CONCLUSION Non-penetrating deep sclerectomy appears to be an efficient and safe surgical alternative to penetrating trabeculectomy in treatment of primary congenital glaucoma. Non-penetrating deep sclerectomy has fewer postoperative complications in comparison to penetrating trabeculectomy with a comparative postoperative reduction in the intraocular pressure and overall success rates.

Abstract
Objective Maintaining intraocular pressure (IOP) is important in preventing ocular complications in patients undergoing ophthalmic surgery for general anesthesia. The effects of non-depolarizing neuromuscular blockers on IOP remain unclear. The present study compared the effects of cisatracurium, rocuronium, and mivacurium on IOP during induction of general anesthesia in vitreous retinal surgery. Materials and Methods In this prospective randomized double-blinded study, 133 patients undergoing vitreous retinal surgery were randomized into one of the three groups: Group cisatracurium (n=45), Group rocuronium (n=44), or Group mivacurium (n=44). Each drug (cisatracurium 0.1 mg kg−1 in Group cisatracurium, rocuronium 0.6 mg kg−1 in Group rocuronium, and mivacurium 0.2 mg kg−1 in Group mivacurium) was administered during induction of anesthesia. IOP and hemodynamic parameters were measured at 1 min before anesthesia induction (T0). Bispectral index (BIS) was maintained between 45 and 55 after propofol administration (T1). Train-of-four stimulation (TOF) was below 0 after muscle relaxant administration (T2) and after laryngeal mask implantation (T3). Results Both ipsi-operative and control-operative IOP at T1, T2, and T3 significantly decreased from the baseline values (T0) in all three groups (P<0.05). The IOP changes between T1 and T2 among three groups were similar (P>0.05). The values of systolic blood pressure (SBP) and diastolic blood pressure (DBP) at T1 and T2 significantly decreased in all three groups compared to T0 (P<0.05). Conclusion Bilateral IOP significantly decreased from the baseline values in all three groups during the induction phase. Cisatracurium, rocuronium, and mivacurium did not induce significant changes in bilateral IOP.

Abstract
Attenuation of an increase in intraocular pressure (IOP) is crucial to preventing devastating postoperative visual loss following surgery. IOP is affected by several factors, including the physiologic alteration due to pneumoperitoneum and patient positioning and differences in anesthetic regimens. This study aimed to investigate the effects of propofol-based total intravenous anesthesia (TIVA) and volatile anesthesia on IOP. We searched multiple databases for relevant studies published before October 2019. Randomized controlled trials comparing the effects of propofol-based TIVA and volatile anesthesia on IOP during surgery were considered eligible for inclusion. Twenty studies comprising 980 patients were included. The mean IOP was significantly lower in the propofol-based TIVA group after intubation, pneumoperitoneum, Trendelenburg positioning, and lateral decubitus positioning. Moreover, mean arterial pressure and peak inspiratory pressure were also lower after intubation in the propofol-based TIVA group. Trial sequential analyses for these outcomes were conclusive. Propofol-based TIVA is more effective than volatile anesthesia during surgery at attenuating the elevation of IOP and should be considered, especially in at-risk patients.

Abstract
PURPOSE Colonoscopy is an endoscopic examination of the bowel. It requires insufflation of the large bowel lumen with gas which leads to intraabdominal hypertension (IAH). There is evidence suggesting that IAH positively correlates with intracranial pressure (ICP) and possibly with intraocular pressure (IOP). The aim of this study was to examine the effect of routine screening colonoscopy performed under sedation on the IOP in healthy individuals. PATIENTS AND METHODS This was a prospective, single site, observational study. Healthy adults undergoing routine colonoscopy performed under sedation including propofol, fentanyl, and midazolam were recruited. Right eye IOP measurements were performed using Tonopen XL® in a left decubitus position at 5 time points during the procedure. Statistical analysis was performed using Student's t-test for paired samples. RESULTS Twenty-three Caucasians were recruited. There are 14 males (60%) with a mean age of 60.4 ± 10.4 years (range 36-74). Colonoscopy was conducted under sedation and completed in 22 subjects. Mean baseline IOP was 19.9 ± 4.7 mmHg, 15.8 ± 4.8 mmHg immediately after sedation, 13.5 ± 2.3 mmHg when the colonoscope had reached the cecum, 15.4 ± 5.0 mmHg 5 min after colonoscopy beginning, and 16.5 ± 5.5 mmHg when located in the rectum. The IOP reduction during the procedure was statistically significant (P < 0.01). CONCLUSION Routine colonoscopy performed under sedation using propofol, fentanyl, and midazolam does not increase the IOP in healthy adults.

Abstract
OBJECTIVE Perioperative visual loss (POVL) is a rare but serious complication in surgical disciplines, especially in spine surgery. The exact pathophysiology of POVL remains unclear, but elevated intraocular pressure (IOP) is known to be part of it. As POVL is rarely described in patients undergoing intracranial or intradural surgery, the aim of this study was to investigate the course of IOP during neurosurgical procedures with opening of the dura mater and loss of CSF. METHODS In this prospective, controlled trial, 64 patients fell into one of 4 groups of 16 patients each. Group A included patients undergoing spine surgery in the prone position, group B patients had intracranial procedures in the prone position, and group C patients were treated for intracranial pathologies in a modified lateral position with the head rotated. In groups A-C, the dura was opened during surgery. Group D patients underwent spine surgeries in the prone position with an intact dura. IOP was measured continuously pre-, peri-, and postoperatively. RESULTS In all groups, IOP decreased after induction of anesthesia and increased time dependently after final positioning for the operation. The maximum IOP in group A prior to opening of the dura was 28.6 ± 6.2 mm Hg and decreased to 23.44 ± 4.9 mm Hg directly after dura opening (p < 0.0007). This effect lasted for 30 minutes (23.5 ± 5.6 mm Hg, p = 0.0028); after 60 minutes IOP slowly increased again (24.5 ± 6.3 mm Hg, p = 0.15). In group B, the last measured IOP before CSF loss was 28.1 ± 5.0 mm Hg and decreased to 23.5 ± 6.1 mm Hg (p = 0.0039) after dura opening. A significant IOP decrease in group B lasted at 30 minutes (23.6 ± 6.0 mm Hg, p = 0.0039) and 60 minutes (23.7 ± 6.0 mm Hg, p = 0.0189). In group C, only the lower eye showed a decrease in IOP up to 60 minutes after loss of CSF (opening of dura, p = 0.0007; 30 minutes, p = 0.0477; 60 minutes, p = 0.0243). In group D (control group), IOP remained stable throughout the operation after the patient was prone. CONCLUSIONS This study is the first to demonstrate that opening of the dura with loss of CSF during neurosurgical procedures results in a decrease in IOP. This might explain why POVL predominantly occurs in spinal but rarely in intracranial procedures, offers new insight to the pathophysiology of POVL, and provides the basis for further research and treatment of POVL.German Clinical Trials Register (DRKS) no.: DRKS00007590 (drks.de).

Abstract
PURPOSE The aim of the present study is to evaluate the effects of deliberate hypotensive anesthesia on intraocular pressure (IOP) and ocular perfusion pressure (OPP) and compare the effects of propofol total intravenous anesthesia (TIVA) and desflurane anesthesia on IOP and OPP. METHODS A total of 50 patients undergoing arthroscopic shoulder surgery in the lateral decubitus position were randomized to receive desflurane or propofol anesthesia. Mean arterial pressure (MAP) was maintained in the range of 60-75 mm Hg during hypotensive anesthesia. IOP was measured using a handheld tonometer at 7 time points: before induction (T1, baseline); immediately after endotracheal intubation (T2); 10 minutes after position change to lateral decubitus (T3); 10, 30, and 50 minutes after the start of hypotensive anesthesia (T4-T6); and at the end of surgery (T7). RESULTS MAP decreased about 35% to 38% during hypotensive anesthesia. Compared to baseline values, the IOP at T6 in dependent and non-dependent eyes decreased by 0.43 and 2.74 mm Hg, respectively in desflurane group; 3.61 and 6.05 mm Hg, respectively in the propofol group. IOP of both eyes in the propofol group was significantly lower than in the desflurane group from T2 to T7. OPP of both eyes in both groups was significantly lower than at baseline, except at T2 in the desflurane group. OPP of both eyes in the propofol group was significantly higher than that in the desflurane group at T5 and T6. CONCLUSIONS Hypotensive anesthesia reduced IOP and OPP, but propofol TIVA maintained higher OPP than desflurane anesthesia. These findings suggest that propofol TIVA can help mitigate the decrease of OPP during hypotensive anesthesia.

Variation in intraocular pressure caused by repetitive positional changes during laparoscopic colorectal surgery: a prospective, randomized, controlled study comparing propofol and desflurane anesthesia.

Abstract
Laparoscopic surgery is often prolonged and requires positional changes to facilitate surgical access. Previous studies reported intraocular pressure (IOP) changes in one fixed position. This study investigated the effect of desflurane and propofol anesthesia on IOP during repeated positional changes. A total of 46 patients undergoing laparoscopic colorectal surgery were randomized into desflurane or propofol groups. IOP was measured using a handheld tonometer at seven time points: before induction (baseline), after endotracheal intubation, after pneumoperitoneum, after the first Trendelenburg and right tilt position, after reverse Trendelenburg and right tilt position, after the second Trendelenburg and right tilt position and before endotracheal extubation. Trendelenburg positioning raised IOP in both groups. In the desflurane group, IOP at the first Trendelenburg position was 6.27 and 8.48 mmHg higher than baseline IOP in left and right eye, respectively; IOP at the second Trendelenburg position was 7 and 9.44 mmHg higher than baseline in left and right eye, respectively. In the propofol group, IOP at the first Trendelenburg position was 2.04 and 4.04 mmHg higher than baseline in left and right eyes, respectively. It was 3.04 and 4.87 mmHg higher than baseline in left and right eye, respectively, at the second Trendelenburg position. In the desflurane group, 56.52% patients exhibited high IOP (≥ 25 mmHg) compared with 13.04% in the propofol group at the second Trendelenburg position in the right eyes (P = 0.005). There was a positive correlation between IOP and peak inspiratory pressure (P < 0.001). Propofol anesthesia mitigated wide variations in IOP caused by repetitive positional changes during laparoscopic colorectal surgery.
